Question

why is the concept of heat important in physics?

why is this concept interesting?

Answer 1

Everything around the world contains heat in it. It is a form of energy. From basic things like walking to something complex like burning, heat is involved. Since physics deals with our basic day to day activities thus heat is important part of physics. The physics concept of thermodynamics is completely based on the concept of heat.

Heat serves as a very interesting concept as it plays significant role in both molecular activities like kinetic theory of gases to macro level things like heat produced due to friction. Trying to reduce the energy losses due to heat helps in conserving energy which in turn increases the efficiency of the machines. Thus understanding heat helps in development of various things.
