• A box filled with particles

• A miniature solar system

According to the Kinetic Molecular Theory, what is true about molecules?

• They are in constant motion

• They are static

• They only move when energy is applied

• They move faster in solids than in gases

What does the Kinetic Molecular Theory explain?

What is not a part of the three theories about matter according to the Kinetic Molecular Theory?

• Matter is made up of small particles

• The space the molecules occupy depends on the space between the molecules

• The molecules are in constant motion

• The molecules are only active during chemical reactions

According to the Kinetic Molecular Theory, how do molecules in a solid behave?

• Molecules are very far apart and in random motion.

• Molecules flow or glide over each other.

• Molecules are in continual motion and are much farther apart than in liquids.

• Molecules are very close to each other due to attraction of charge and have an ordered arrangement.

What is a unique characteristic of molecules in a liquid state?

• They have enough kinetic energy to move out of an ordered arrangement.

• They are in continual motion and are much farther apart than in solids.

• They are very close to each other due to attraction of charge.

• They are very far apart and in random motion like in plasma.

How does the kinetic energy of molecules in a gas compare to that in solids and liquids?

• It is less than in solids but more than in liquids.

• It is the same as in solids and liquids.

• It is greater than in solids and liquids.

• It is only greater than in solids but less than in liquids.

What happens to the movement of molecules when pressure is increased?

• The movement of molecules will decrease.

• The movement of molecules will stay the same.

• The movement of molecules will increase.

• The molecules will stop moving.

What is one way plasma differs from liquids, solids, and gases?

• Plasma molecules are closer to each other due to attraction of charge.

• Plasma has a charge and can break electrons away from atoms.

• Plasma molecules have less kinetic energy than those in solids.

• Plasma molecules are in an ordered arrangement.
