Quiz on Heat and Thermal Energy

What is heat?

• A type of energy

• A way of measuring the amount of thermal energy in an object

• The transfer of thermal energy

• The transfer of electrical energy

Which of the following is important to generating heat?

• Friction

• Chemical reactions

• Sunlight

• All of the above

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

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

• Rubbing generates electric energy, which transforms into thermal energy

• Rubbing causes 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 to a hot object

• A cold to a cool object

• A hot to a cold object

• A hot to a hotter object

What tool do we use to measure the temperature of a substance?

• A ruler

• A thermometer

• A graduated cylinder

• A scale

• True

• False

• True

• False

Pressure will have no impact on how particles interact.

• True

• False
