Physics Vocabulary- Chapter 22 Heat Transfer

In heat, energy transfer from particle within certain materials, or from one material to another when the two are in direct contact.
material through which heat can be transferred
a means of heat transfer by movement of the heated substance itself, such as by currents in a fluid
greenhouse effect
The warming effect whose cause is that short-wavelength radiant energy from the sun can enter the atmosphere and be absorbed by the earth more easily than long wavelength energy rom the earth can leave.
A material that is a poor conductor of heat and that delays the transfer of heat.
Newton's law of cooling
The rate of cooling of an object is approximately proportional to the temperature difference ∆T between the object and it's surroundings. (rate of cooling ~ ∆T)
radiant energy
Any energy, including heat, light, and X rays, that is transmitted by radiation. It occurs in the form of electromagnetic waves.
Energy transmitted by electromagnetic waves.
terrestrial radiation
Radiant energy emitted from the earth.
