---|---|
temperature | measure of how hot or cold something is |
Thermal energy | energy that comes from heat |
Heat | high temperature/quality of being hot |
Conduction | transfer of thermal energy by the collisions of particles |
convection | transfer of thermal energy by MOVEMENT of particles without particles |
radiation | transfer of thermal energy by WAVES without particles |
conductor | material allowing thermal energy to be transferred easily |
insulator | material NOT allowing thermal energy to be transferred easily |
