Properties of Water / Osmosis and Diffusion

What is Diffusion?

Movement of particles or molecules from an area of high concentration to an area of low concentration

Two solutions that have an equal concentration of solutes

A substance dissolved in a solution

What is Osmosis?

A solution that has a higher concentration of solutes than another.

Diffusion of water across a selectively permeable membrane

A solution that has a lower concentration of solutes than another.

What is Hypertonic?

Egulates and controls what enters or leaves the cell

A solution that has a lower concentration of solutes than another.

A membrane that allows certain materials to pass through, but not others.

What is Hypotonic?

Substances that easily mix with water.

A solution that has a lower concentration of solutes than another.

Movement of molecules or ion into or out of the cell against its concentration gradient (from low to high) and requires an input of energy

If something can stick to other objects, is it adhesive or cohesive?

Adhesive

Cohesive

If a substance is the substance in which the solute dissolves in, what is it?

Solvent

Mixture

What is Surface Tension?

A measure of how difficult it is to break the surface of a liquid and is caused by cohesion

A weak acid or base that can react with a strong acid or base to prevent sudden changes in pH

He amount of energy needed to increase the temperature of a substance

What is Heat Capacity?

A lit bonfire

How much heat that can be held until overheating occurs

The amount of energy needed to increase the temperature of a substance

What is Water Density?

The weight of the water per its unit volume, which depends on the temperature of the water.
