Heat Transfer Chapter 22

Front 1

In heat enegy, the transfer from particle to particle within certain materials, or from one material to another when the two are in direct contact.

Back 1

conduction

Front 2

Material through which heat can be transferred.

Back 2

conductor

Front 3

A means of heat transfer by movement of the heated substance itself, such as by currents in a fluid.

Back 3

convection

Front 4

the warming effect whose cause is that short- wavelength radiant energy from the sun can enter the atmosphere and be absorbed by Earth more easily than long-wavelength energy from Earth can leave.

Back 4

Greenhouse effect

Front 5

A material that is a poor conductior of heat and that delays the transfer of heat.

Back 5

insulator

Front 6

The rate of cooling an object- whether by conduction, convection, or radiation- is approximately proportional to the temperature difference between the object and its surroundings.

Back 6

Newtons Law of cooling

Front 7

any energy, including heat, light, X-rays, that is transmitted by radiation. It occurs in the form of electromagnetic waves.

Radiant Energy

Front 8
