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

• More rapidly at an increased diestance from each other.
• More rapidly with less distance between each other.
• More slowly with a greater distance between each other.
• More slowly with a reduced distance between each other.

What is the difference between particles in a gas and a solid?

• gas particles are closer together
• solid particles move faster than gas particles
• solid particles expand on heating
• gas particles have more kinetic energy than solid particles

The pressure inside the balloon will:

• Decrease

• Increase

• Remain the same

• Not enough information to formulate an answer

The reason gases can be compressed is because:

• The particles are very close together.

• The particles are merely vibrating.

• The particles are unable to move.

• The particles are very far apart.
