Thermal energy
Question | Answer |
---|---|
Thermal Energy | the sum of kinetic and potential energy of all the particles on an object |
Temperature | the measure of the average kinetic energy if particles in an object |
Heat | the transfer of energy from one object to another |
Transfer of thermal energy | there is no such thing as cold |
Conduction | transfer of energy through matter by direct contact of particles |
Convection | transfer of energy through the movement of heated particles |
Radiation | Transfer of energy through electromagnetic waves occurs fastest in gasses |
Conductors | materials that let heat flow easily |
Insulators | materials that don't allow heat to flow easily |
Specific Heat | the amount of heat need to raise he temperature of a 1 kg of a material by 1 degree cork |
