Front

What happens to particles when more heat is supplied to a system?

Back

They would speed up.

Front

If particles in an object are moving very quickly, what can be inferred about the object's temperature?

Back

The object is probably hot.

Front

Which sample of water heats up faster when the same amount of heat is applied: 100 mL or 1000 mL?

Back

Front

What is thermal energy?

Back

The total kinetic energy of particles in a substance.

Front

Explain the relationship between heat and particle movement.

Back

As heat increases, particle movement increases.

Front

What is the effect of temperature on the speed of particles?

Back

Higher temperature results in faster particle movement.

Front

What is the difference between kinetic and potential energy?

Back

Kinetic energy is energy of motion; potential energy is stored energy.
