Question

why when we rub our hands, they get warm​

Answer 1

Answer:

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

When we rub our hands Friction is produced. Production of friction produces heat energy. This makes our hands warmer when we rub them against each other.

Fun fact: We cannot produce more than 9 deg Celsius of heat by rubbing our hands. That is, if original temp was 25 degrees then we can increase it only to 34 degree
