CLEP natural science- Physics
Study online at https://quizlet.com/_355rd
1. Heat energy that flows from an object that is warm to an object that is cooler.
2. Temperature the measure of the average kinetic energy of a substance
3. Average kinetic The energy of the motion of the atoms and molecules in a substance. The lower
energy temperature, the slower particle motion (less energy); The higher the temperature,
the faster the motion (more energy)
4. Absolute zero The coldest temperature, 0 Kelvin, that can be reached. It is the hypothetical
temperature at which all molecular motion stops.
5. Radiation energy that is radiated or transmitted in the form of rays or waves or particles.
6. Convection the movement of energy by the movement of matter, usually through currents. eg.
convection moves warm air up, while cool air sinks. In a fluid, the heat will move
with the fluid.
7. Conduction the transfer of thermal energy from one substance to another through direct
contact
8. specific heat The measure of a substance's ability to retain energy. The heat required to raise
the temperature of one gram of a substance one degree centigrade.
9. Law of thermody- the interaction between heat and work (energy) in the universe
namics
10. Law of conser- First law: matter and energy cannot be created or destroyed
vation of matter
and energy
11. Law of entropy Second law: whenever energy is exchanged, some energy becomes unavailable
for use (entropy increases)
