Terms | Definitions |
|---|---|
 three types of heat transfer | conduction, convection, radiation |
| Conduction | when two things transfer heat through physical contact |
| Convection | the transfer of heat by moving a heated substance from one place to another |
| Radiation | The transfer of heat through transforming the heat into electromagnetic waves |
| Thermodynamics | Deals with the relations ship of heat transfer between other forms of energy. Study of the effects of work, heat and energy on a system. The transfer of energy through heat. The way heat is used as an energy resource |
| Kinetic | Energy being used, energy in motion |
| Potential | Energy being stored and has the ability to be used, the energy an object posseses |
| 1st Law of Thermodynamics | Energy cannot be created of destroyed, only transferred or transformed. The total amount of energy remains constant in the universie |
| 2nd Law of thermodynamics | Transfer of heat goes from higher to lower temperatures until an equilibrium is achieved, enthropy |
| Closed system | does not allow mass to flow, only allows transfer of heat energy and work |
| Open system | allows mass to flow |
| Enthalpy | the amount of usable heat energy in a system |
| Entropy | The degree of randomness or disorganization of certain substance at a certain temperature |
