Front

What happens to the average kinetic energy of matter when it is heated?

Back

It increases.

Front

Which of the following is NOT a part of the Kinetic Theory of Matter?

Back

Occasionally, particles stop moving.

Front

At what temperature does matter change phases from a solid to a liquid?

Back

Melting Point.

Front

Which of the following states of matter has the LOWEST level of energy?

Back

Solid.

Front

When thermal energy is added to a substance, the substance's particles move:

Back

More rapidly at an increased distance from each other.

Front

What is the Kinetic Theory of Matter?

Back

It states that all matter is made up of tiny particles that are in constant motion.

Front

What happens to the particles in a solid when it is heated?

Back

They vibrate faster and may eventually break free to become a liquid.

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 the boiling point?

Back

The temperature at which a liquid turns into a gas.

Front

What state of matter has particles that are far apart and move freely?

Back

Gas.
