Difference between Temperature and Heat

Heat is a form of (Thermal) energy due to the kinetic energy of molecules in a substance. Temperature is measure of hotness or coldness of a body. Temperature is a measurement of the average kinetic energy of the molecules in an object or system.

Mathematically, dQ = k dT; where dQ is the change in heat content, k is a constant of proportionality, and dT is the change in temperature (usually in degrees Kelvin).
