Define Heat.

The quality of being hot; high temperature.

The degree or intensity of heat present in a substance or object, especially as expressed according to a comparative scale and shown by a thermometer or perceived by touch.

Define Convection.

The emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles that cause ionization.

The movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat.

Define Radiation.

The emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles that cause ionization.

Define Conduction.

The process by which heat or electricity is directly transmitted through a substance when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material.

The emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles that cause ionization.

Whats a Kelvin Scale?

A scale of temperature with absolute zero as zero, and the triple point of water as exactly 273.16 degrees.

Just a scale that measures water.

Define Absolute Zero.

The lowest temperature possible.

The lowest temperature that is theoretically possible, at which the motion of particles that constitutes heat would be minimal. It is zero on the Kelvin scale, equivalent to –273.15°C or –459.67°F.

Define Specific Heat.

A scale of temperature with absolute zero as zero, and the triple point of water as exactly 273.16 degrees.

The heat required to raise the temperature of the unit mass of a given substance by a given amount (usually one degree).

Open Ended Response: You are assigned a project that requires you to boil an egg. The question tells you to record if you are using convection, conduction, or radiation. When you are boiling that egg, are you using conduction, convection, radiation, or all? The answer should have an explanation and should be a paragraph long (5-7 Sentences).
