What happens to energy when it moves from one part of a system to another?

• It disappears and is gone forever.
• It creates more energy as it moves.
• It changes into light and heat only.
• It is neither created nor destroyed; it just moves around.

Why does the transfer of energy between two things stop?

• When one thing becomes colder than the other.
• When both things have the same amount of energy.
• When the energy runs out.
• When the energy is created.

Why do molecules change speed?

• Because of changes in temperature.
• Because they like to move faster sometimes.
• Because they run out of energy.
• Because they are always at the same speed.
