In thermodynamics, heat and temperature are closely related concepts with precise definitions.
- Heat, \text qqstart text, q, end text, is thermal energy transferred from a hotter system to a cooler system that are in contact.
- Temperature is a measure of the average kinetic energy of the atoms or molecules in the system.
- The zeroth law of thermodynamics says that no heat is transferred between two objects in thermal equilibrium; therefore, they are the same temperature.

- We can calculate the heat released or absorbed using the specific heat capacity C the mass of the substance \text mmstart text, m, end text, and the change in temperature ΔT in the following equation:
- q = m × C × ΔT
