|---|---|
 Conduction | the transfer of thermal energy from one substance to another through direct contact |
| convection | the transfer of thermal energy by the circulation or movement of a liquid or gas |
| absolute zero | (cryogenics) the lowest temperature theoretically attainable (at which the kinetic energy of atoms and molecules is minimal) |
| Radiation | energy that is radiated or transmitted in the form of rays or waves or particles |
| specific Heat | the amount of heat required to raise the temperature of 1g of a substance 1 degree Celsius |
| temperature | the degree of hotness or coldness of a body or environment (corresponding to its molecular activity) |
| Heat energy | a form of energy that is transferred by a difference in temperature |
| Combustion | a process in which a substance reacts with oxygen to give heat and light |
| melting point | the temperature at which a substance changes from a solid to a liquid |
