Thermal Energy | is the sum of the kinetic and the potential energy of the particles that make up a material |
Temperature | is a measure of the average kinetic energy of the particles in a sample of matter |
Heat | the movement of thermal energy from a warmer to a cooler object |
Radiation | the transfer of termal energy from one material to another by electromagnetic waves |
Conduction | the transfer of thermal energy by collisions of particles |
Thermal Conductor | a material in which heat flows easily |
Specific Heat | the amount of thermal energy needed to increase the temperature of 1 kg of a material by 1 degree Celcius |
Thermal Contraction | is a decrease in a material's volume when its temperature decreases |
Thermal Expansion | an increase in the volume of a material as its temperature increases |
Convection | the transfer of thermal energy by the movement of particles from one part of a material to another |
Convection Current | the cyclic movement of fluids because of convection. |
Thermal insulator | a material which prevents the flow of heat |
