Item EG028004: For two balloons that contain the same amount of air, the air with the lower temperature has less thermal energy than the air with the higher temperature.
Balloon 1 and Balloon 2 are filled with the same amount of air. The air in Balloon 1 is cooled so that it is at a lower temperature than the air in Balloon 2. The air in which of these balloons has less thermal energy?
- The air in Balloon 1 has less thermal energy.
- The air in Balloon 2 has less 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.
