Heat is transferred by three different methods: conduction, convection, and radiation The transfer of heat Q that leads to a change Δ T in the temperature of a body with mass m is Q = m c Δ T , where c is the specific heat of the material

Absolute zero is the temperature at which there is no molecular motion There are three main temperature scales: Celsius, Fahrenheit, and Kelvin

heat — transfer of thermal (or internal) energy due to a temperature difference. thermal energy — average random kinetic energy of a molecule or an atom. Kelvin — unit on the Kelvin temperature scale; note that it is never referred to in terms of “degrees” Kelvin. specific heat — amount of heat necessary to change the temperature of 1.00 kg of a substance by 1.00 °C.
