Question

Why do we feel warm when we rub our hands together and touch our cheeks?

Answer 1

1. When we rub our hands together, our hands get warm due to friction.
2. Friction is defined as the resistance offered by the surfaces that are in contact when they move past each other.
3. Friction produces heat between two surfaces when they are rubbed over each other.
4. Hence, when we rub our hands together and touch our cheeks we feel warm.
