Question

Why do your palms feel warm when you rub them?​

Answer 1

Explanation:

When you rub your hands together, the action of scraping the surface of your skin back and forth against each other causes the molecules in your skin to move a little faster. The faster that molecules move, the higher the temperature. So the friction of rubbing your hands together makes them feel warmer.

Answer 2

Explanation:

When we rub our palms, frictional force is applied. Friction produces heat. So, our palms feel warm when we rub them.
