Some students want to demonstrate thermal expansion. They devise the following method: A large black balloon is taken to a shady area and filled with cool air. The balloon is then taken to a bright, sunny location. After a short time, the balloon begins to expand. What explanation does this investigation verify?

• A balloon filled with cool air will rise into the atmosphere.

• As particles gain energy, the material takes up more space.

• The air inside the balloon lost energy.

• The sunlight caused the air in the balloon to contract

Examine the model. The particles are undergoing a change in energy. Which statement best describes what is taking place in the images?

• The kinetic energy of the particles on the right is the greatest of the three images of particles.

• The particles in the middle have more kinetic energy than the particles on the right.

• The particles in the middle have less space between them than the particles on the left, which means they have more kinetic energy.

• The particles on the left have less energy than the particles in the middle.

SHORT ANSWER: Most highways are built with expansion joints that can move back and forth. What is the reason for this?

• So that they look cool.

• To prevent floods.

• To allow roads to expand and contract with temperature changes.

• To slow down cars.

SHORT ANSWER: Think of a time where you noticed a change of state involving ice. Explain what happened using the terms temperature, particle motion, and energy.

• Ice melts out of the freezer because as temperature rises the particles gain more energy.

• Ice freezes out of the freezer because the temperature drops outside the freezer and the particles gain less energy.

• Water boils when heated because as the temperature rises the particles loose energy.

• Water boils when cooled because as the temperature lowers the particles gain energy.
