In heat, energy transfer from particle within certain materials, or from one material to another when the two are in direct contact.
a means of heat transfer by movement of the heated substance itself, such as by currents in a fluid
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.
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)
Any energy, including heat, light, and X rays, that is transmitted by radiation. It occurs in the form of electromagnetic waves.
