Front

What is kinetic energy?

Back

The energy an object possesses due to its motion.

Front

What happens to the particles in a substance as it heats up?

Back

They move faster and spread apart.

Front

What is the relationship between temperature and kinetic energy?

Back

As temperature increases, the average kinetic energy of the particles increases.

Front

What is potential energy?

Back

The energy stored in an object due to its position or arrangement.

Front

How does the kinetic energy of particles in a solid compare to that in a gas?

Back

Particles in a solid have less kinetic energy than those in a gas.

Front

What occurs to the kinetic energy of particles when a substance cools down?

Back

The kinetic energy decreases, and the particles move slower.
