When you rub your hands together, you generate heat. How is this heat generated?

• Friction (from rubbing hands) transforms mechanical energy into thermal energy

• Rubbing generates electric energy, which transforms into thermal energy

• Rubbing cause potential energy to transform into kinetic energy

• Chemical reactions take place in your hands, which produce thermal energy

Thermal energy always transfers from ___________________.

• a cold object to a hot object

• a cold object to a cool object

• a hot object to a cold object
