Thermal energy is responsible for the temperature of a system, and is considered as a part of the total energy of a system that is the sum of potential energy and kinetic energy. Sometimes it is termed as internal energy. The notation for thermal energy is Q. It can be directly proportional to the mass of a substance, specific heat and the temperature difference. SI unit of thermal energy is Joules(J). The formula for finding thermal energy is given as,
Where Q is the thermal energy, m is the mass of the given substance, c is the specific heat and ΔT is the temperature difference.
