Which state of matter has a definite volume but no definite shape?
Liquid
Plasma
Solid
Gas
Liquids maintain a constant volume while adapting their shape to the container they occupy. They lack the rigid structure of solids but are not easily compressible like gases. This behavior is due to moderate intermolecular forces that allow molecules to move past one another while remaining close together. .
Which property of a liquid measures its resistance to flow?
Viscosity
Density
Vapor pressure
Surface tension
Viscosity quantifies a liquid's internal friction and resistance to flow. Higher viscosity liquids, like honey, flow much more slowly than low-viscosity liquids, like water. Temperature and molecular structure strongly influence viscosity. .
Which state of matter is easily compressible and completely fills any container?
Plasma
Liquid
Gas
Solid
Gases exhibit high compressibility and full occupancy of containers because their molecules are widely spaced and move freely. They expand to fill the volume available, regardless of container shape. These properties arise from weak intermolecular forces and high kinetic energy of gas particles. .
Insects like water striders can walk on water because of which phenomenon?
Buoyancy
Viscosity
Cohesion
Surface tension
Surface tension is the energy required to increase a liquid's surface area, creating a 'skin' at the interface that supports lightweight objects. Cohesive forces between water molecules generate this tension, allowing insects to walk on water without breaking the surface. .
Boyle's law describes the relationship between which two variables at constant temperature?
Pressure and number of moles
Pressure and temperature
Pressure and volume
Volume and temperature
Boyle's law states that the pressure and volume of a fixed amount of gas at constant temperature are inversely proportional (P ? 1/V). As volume decreases, pressure increases and vice versa. This fundamental gas law holds when temperature and amount of gas remain unchanged. .
What is the SI unit of pressure?
Pascal
Bar
Torr
Atmosphere
The pascal (Pa) is the SI derived unit of pressure, defined as one newton per square meter. It quantifies the force applied perpendicular to a surface per unit area. Other units like atmospheres and torrs are commonly used in specialized contexts. .
How does temperature generally affect the viscosity of a liquid?
Decreases viscosity
Increases viscosity
Increases surface tension instead
No effect on viscosity
As temperature rises, the kinetic energy of liquid molecules increases, reducing intermolecular attractions and allowing molecules to flow more freely. This decrease in molecular cohesion lowers viscosity. Most common liquids become less viscous when heated. .
When the rate of evaporation equals the rate of condensation in a closed container, this state is called:
Dynamic equilibrium
Boiling point
Phase transition
Static equilibrium
Dynamic equilibrium in a closed system occurs when molecules evaporate and condense at equal rates, resulting in a stable vapor pressure. There is continuous molecular exchange between phases, but no net change in amounts. This principle underlies vapor - liquid equilibrium in thermodynamics. .
On a pressure - temperature phase diagram, the point at which liquid and gas phases become indistinguishable is called the:
Critical point
Triple point
Boiling point
Sublimation point
The critical point marks the combination of temperature and pressure above which liquid and gas phases are no longer distinct. Beyond this point, the substance becomes a supercritical fluid with unique properties. It is a fundamental concept in phase behavior. .
Which equation represents the ideal gas law?
P + a(n/V)² = RT
P/T = constant
PV = nRT
V/T = k
The ideal gas law combines Boyle's, Charles's, and Avogadro's laws into PV = nRT, relating pressure, volume, and temperature for an ideal gas. Here, R is the universal gas constant. This model assumes no intermolecular forces and negligible molecular volume. .
Which law states that the solubility of a gas in a liquid is directly proportional to the partial pressure of that gas above the liquid?
Raoult's law
Charles's law
Henry's law
Dalton's law
Henry's law describes how the concentration of a dissolved gas is proportional to its partial pressure in the gas phase above the solvent. It is fundamental in understanding gas absorption in liquids. Deviations occur at high pressures or with reactive solutes. .
In a mixture of ideal gases, what is the partial pressure of a component gas?
Total pressure minus vapor pressure
The pressure remaining after mixing
Pressure at which gas condenses
The pressure due to one gas component
Partial pressure is the hypothetical pressure a single gas would exert if it occupied the entire volume alone. Dalton's law states that total pressure is the sum of all partial pressures in a mixture. It is key to calculations in gas mixtures. .
Why do gas bubbles expand as they rise toward the surface of a liquid?
Temperature increases
Surface tension increases
Liquid density increases
Ambient pressure decreases
Hydrostatic pressure in a liquid decreases with decreasing depth. As bubbles ascend, the external pressure drops, allowing the gas inside to expand in accordance with Boyle's law. The temperature change is often negligible compared to pressure effects. .
Which factor is primarily responsible for deviations of real gases from ideal behavior at high pressures?
Intermolecular forces
Color of the gas
Molecular shape
Ionization energy
At high pressures, molecules are forced closer together, making intermolecular attractions significant. These forces reduce the pressure exerted on container walls compared to ideal predictions. Finite molecular volume also plays a role, but attractions dominate at moderate high pressures. .
According to Raoult's law, what happens to the vapor pressure of a solvent when a non-volatile solute is added?
It becomes zero
It remains the same
It increases
It decreases
Raoult's law states that the vapor pressure of a solvent above a solution is the pure solvent's vapor pressure multiplied by its mole fraction. Adding a non-volatile solute lowers the mole fraction of solvent, thus reducing vapor pressure. This phenomenon explains colligative properties like boiling point elevation. .
What term describes the highest temperature at which a substance can exist as a liquid regardless of pressure?
Boiling point
Sublimation temperature
Critical temperature
Triple point temperature
The critical temperature is the maximum temperature at which a liquid phase can exist; above this, no amount of pressure will liquefy the gas. At the critical point, liquid and gas phases become indistinguishable. It is a key parameter in supercritical fluid applications. .
Which dimensionless quantity predicts whether fluid flow will be laminar or turbulent?
Nusselt number
Prandtl number
Mach number
Reynolds number
The Reynolds number compares inertial forces to viscous forces in a fluid. Low values indicate laminar flow, while high values denote turbulent flow. It is widely used in fluid dynamics and engineering. .
Which type of intermolecular force largely contributes to the high viscosity of glycerol?
Ionic bonding
London dispersion forces
Hydrogen bonding
Dipole - dipole interactions
Glycerol molecules form extensive hydrogen bonds due to multiple hydroxyl groups. These strong, directional interactions significantly increase resistance to flow, resulting in high viscosity. London dispersion and dipole interactions are weaker contributors in this case. .
Which description best characterizes a supercritical fluid?
An ionized gas at high pressure
A gas at very high temperature
A state above the critical point with properties of both liquids and gases
A mixture of liquid and gas
A supercritical fluid exists beyond its critical temperature and pressure, where distinct liquid and gas phases do not exist. It combines liquid-like density with gas-like diffusivity. This unique behavior enables applications in extraction and materials processing. .
In the van der Waals equation (P + a(n/V)²)(V - nb) = nRT, the constant b accounts for:
Excluded volume of molecules
Attractive intermolecular forces
Temperature dependence of pressure
Surface tension effects
In the van der Waals equation, b represents the finite volume excluded by gas molecules, correcting for the space they occupy. This adjustment improves predictions at higher pressures where molecular volume matters. The constant a corrects for intermolecular attractions. .
In supercritical CO? extraction processes, increasing which parameter most directly enhances solvent density and solvation power?
Pressure
Temperature
Solute concentration
Flow rate
Raising the pressure in a supercritical CO? system increases the fluid's density, improving its ability to dissolve and extract target compounds. Temperature also affects solubility but has a more complex relationship. Pressure control is the primary method for tuning solvating properties. .

Cheat Sheet

  1. Intermolecular Forces in Liquids -

    Understanding hydrogen bonding, dipole - dipole attractions, and London dispersion forces is key to grasping facts on liquids. For example, water's high surface tension is due to strong H-bonds, often remembered with the mnemonic "Sticky H2O." These forces also influence viscosity and wetting behavior in everyday solutions.

  2. Vapor Pressure and Boiling Point -

    Vapor pressure and boiling point are related by the Clausius - Clapeyron equation, ln(P2/P1)= - ΔHvap/R(1/T2 - 1/T1), which predicts how pressure changes with temperature. At 1 atm, water boils at 100°C because its vapor pressure equals external pressure at that temperature. Recognizing this relationship is essential for a thorough states of matter quiz.

  3. Ideal vs. Real Gas Behavior -

    The ideal gas law, PV=nRT, models gases under low-pressure, high-temperature conditions, while the van der Waals equation, (P+a(n/V)^2)(V - nb)=nRT, accounts for molecular volume and intermolecular attraction. Remember the quick tip "FLIP" to recall when to use real gas corrections: Fails Low-Pressure Ideal Predictions. Mastering these equations will boost your score on any chemistry trivia quiz.

  4. Reading Phase Diagrams -

    Phase diagrams map matter states quiz conditions showing solid, liquid, and gas regions, plus critical and triple points where unique phase changes occur. Water's triple point at 0.01°C and 0.006 atm is used in calibrating temperature standards. Visualizing these diagrams helps in understanding how pressure and temperature govern state transitions.

  5. Factors Affecting Evaporation -

    Evaporation rates depend on temperature, surface area, and humidity according to kinetic theory: only molecules exceeding the escape energy can vaporize. The acronym "HAT" (Humidity, Area, Temperature) can help recall these factors during a solid liquid gas quiz. Controlling these variables is crucial in processes like freeze-drying and industrial coating.
