Physics

Physics - Semester 2 - Chapter 22 Key Terms

TermDefinition
conduction in heat, energy transfer from particle to particle within certain materials, or from one material to another when the two are indirect contact
conductor material through which heat can be transferred
convection a means of heat transfer by movement of the heated substance itself, such as by current 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 Earth more easily than long-wavelength energy from Earth can leave
insulator 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 - whether by conduction, convection, or radiation - is approximately proportional to the temperature difference between the object and its surroundings
radiant energy any energy, including heat, light, and X-rays, that is transmitted by radiation. it occur in the form of electromagnetic waves.
radiation energy transmitted by electromagnetic waves
terrestrial radiation radiant energy emitted from Earth
