Question

the photograph above is of the annual albuquerque balloon festival. the balloons rise because the air in the balloons is heated. heating a gas increases which of the following:
o the energies of the electrons in the bonds of the air molecules
o the kinetic energy, k of the air molecules
o both the energies of the electrons in the bonds of the air molecules and the kinetic energy of the air molecules

Explanation:

Heating a gas increases the kinetic energy of its molecules. The energy of electrons in the bonds of air - molecules is not directly affected by simple heating in the context of a hot - air balloon rising. Heating the air in the balloon makes the air less dense than the surrounding cooler air, causing the balloon to rise due to buoyancy. The kinetic energy of air molecules increases with heating.

Answer:

The kinetic energy, K of the air molecules
