How is heat similar to and different from internal energy?

Heat is similar to and different from internal energy

Explanation:

Similarity:

First thing to remember is that heat and internal energy are both different forms of energy. Secondly, heat is directly proportional to internal energy. When you provide heat to the system, its internal energy will increase. So, heat is the part of internal energy.

Difference:

Internal energy is the summation of kinetic and potential energy of a system, means it depends upon movement of particles as well as the particular position of the system while heat is the transfer of the energy due to difference of degree of hotness and coldness of body or a system.
