Heat & Temperature
Term | Definition |
---|---|
Temperature | Measure of the average KINETIC ENERGY of the particles that make up an object... Measure of how hot or cold something is |
Absolute Zero | Temperature at which all molecular motion stops |
Heat | Energy transferred between objects that are at different temperatures (ALWAYS from high to low temperature) |
Thermal Conduction | Transfer of energy as heat through a material |
Convection | Movement of matter due to differences in density that are caused by temperature variations |
Convection Current | VERTICAL movement of air currents due to temperature variations... Hot air rises above cool air |
Radiation | Energy that is transferred as electromagnetic waves |
Conductor | Material through which energy can EASILY be transferred as heat |
Insulator | Material that is a POOR conductor through which energy can NOT be easily transferred |
