Thermal Energy

What happens to particles as they cool down?

• They slow down
• Nothing
• They don't move
• They speed up

Mittens help keep your hands warm in winter because:

• They are conductors of heat.
• They are fuzzy.
• They are conductors of electrical energy.
• They are insulators.

What happens to particles as they heat up?

• They slow down
• Nothing
• They don't move
• They speed up

An object that doesn't conduct heat well is known as:

• a conductor
• an insulator
• conduction
• insulation

The Law of Conservation of Energy states:

• Energy can created or destroyed but not transformed 
• Energy cannot be created or destroyed, it can only transformed
• Energy can't be created, destroyed or transformed

Moving objects have kinetic energy

• TRUE
• FALSE

What is the Kinetic Molecular Theory of Heat?

• that molecules in a substance go slower as temperature increases.

• that molecules in a substance go faster as temperature increases.

• that temperature has nothing to do with the speed of molecules.
