| Question | Answer |
|---|---|
| temperature | a measure of how hot (or cold) something is; specifically, a measure of the average kinetic energy of the particles in an object |
| thermal epansion | an increase in response to an increase in the temperature of the substance |
| absolute zero | the temperature at which molecular energy is at a minimun (0 K on the Kelvin scale or -273.16*C on the Celsius scale.) |
| Heat | the energy transferred between objects that are at different temperature |
| thermal energy | the kinetic energy of a substance's atoms |
| thermal conduction | the transfer of energy as heat through a material |
| thermal conductor | a material through which energy can be transferred as heat |
| thermal insulator | a material that reduces or prevents the transfer of heat |
| convection | the transfer of thermal energy by the circulation or movement of a liquid or gas |
| radiation | the transfer of energy as electronmagnectic waves |
| specific heat | the quantity of heat required to raise a unit mass of homogeneneous material 1 K or 1*C in a specified way given constant pressure and volume |
| state of matter | the physical forms of matter, which include solid, liquid, and gas |
| change of state | the change of a substance from one physical state to another |
| insulation | a substance that reduces the transfer of electricity, heat, or sound |
| thermal pollution | a temperature increase in a body of water that is caused by human activity and that has a harmful effect on water quality and on the ability of the body of water to support life |
