Temperature | is a measure of the average kinetic energy of the particles in an object. |
Thermal expansion | An increase in the size of a substance in response to an increase in the temperature of the substance |
Absolute zero | the temperature at which molecular energy is at a minimum (0 K on the Kelvin scale or -273.16 °C on the Celsius scale) |
Heat | the energy transferred between objects that are at different temperatures |
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 movement of matter due to differences in density; the transfer of energy due to the movement of matter |
radiation | the transfer of energy as electromagnetic waves |
Specific heat | the quantity of heat required to raise a unit mass of homogeneous material 1 K or 1 ºC in a specified way given constant pressure and volume |
states 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 |
heat engine | a machine that transforms heat into mechanical energy, or work |
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 that body of water to support life |
