Hint: In this question we will use the concept of friction force that is when two raw surfaces move against each other in contact, a force is exerted between them which resists this motion. That is called the force of friction.

Complete step-by-step answer:

Friction is a force contrasting motion between some touching surfaces. Might tension work for or against us. Putting sand on an icy pavement, for example, reduces traction and you are less likely to fall. On the other hand, too much friction will cause the parts to wear out between moving parts in a car engine.

Friction occurs because there's no perfectly smooth surface. Also surfaces that look smooth to the unassisted eye, when viewed under a microscope, make appear rough or bumpy.
Friction is produced from surface irregularities. So they generate heat as these surfaces rub against each other. And in those irregularities the heat gets trapped.

Note: This is an illustration of frictional force when two bodies are in contact with each other, electromagnetic forces work between the charged particles on the bodies' surfaces. Consequently, each body exerts one contact force on the other. The magnitudes of the contact forces acting on both bodies are identical, but their movements are opposite and thus Newton's third law is obeyed by the contact forces.
