Thermal Expansion

Which statement is true about how gas particles behave? - Choose all the TRUE statements

• When the balloon was placed in the freezer, the gas particles moved slower, closer together, and thermal contraction occurred.

• When the balloon returned to room temperature, the gas particles moved faster, farther apart, and thermal expansion occurred.

• Thermal expansion and contraction only happen in solids and not in gases.

Which best explains why a hot air balloon floats?

• The heated air expands to fill the balloon. The air in the balloon is now less dense than the surrounding air, causing the balloon to rise. This is an example of thermal expansion.

• The heated air expands to fill the balloon. The air in the balloon is now more dense than the surrounding air, causing the balloon to rise. This is an example of thermal expansion.

• The heated air contracts to fill the balloon. The air in the balloon is now denser than the surrounding air, causing the balloon to rise. This is an example of thermal contraction.
