Balloon 1 and Balloon 2 are filled with the same amount of air. The air in Balloon 2 is cooled so that it is at a lower temperature than the air in Balloon 1. The air in which of these balloons has more thermal energy?

• The air in Balloon 1 has more thermal energy.

• The air in Balloon 2 has more thermal energy.

• The air in Balloon 1 and the air in Balloon 2 have the same amount of thermal energy.

• Neither the air in Balloon 1 nor the air in Balloon 2 has any thermal energy.

On the cold day, the smell reached the student with the stopwatch slower than on the warm day. What does this data provide evidence of?

• On a cold day, the molecules of gas in the room are lighter and move faster.

• On a cold day, more energy is transferred to the gas in the container.

• On a cold day, the molecules of gas in the room have less kinetic energy on average.

• On a cold day, less energy was needed to move the gas across the room.
