You have a balloon that is filled with 1000 cm3 of air. The balloon is inside your house where the temperature is 20°C. You take the balloon outside where the air temperature is 10°C. Assume the pressure on the air inside the balloon remains constant. Select all of the correct descriptions below for what happens to the air in the balloon.

When the balloon is outside the house, it has a volume less than 1000 cm^3.

When the balloon is outside the house, it has a volume greater than 1000 cm^3.

Heat energy was added to the air in the balloon.

Heat energy was removed from the air in the balloon.

The air in the balloon did work on the atmosphere.

The atmosphere did work on the air in the balloon.

The first option is correct.

Heat energy was removed from the air in the balloon.

The air in the balloon did work on the atmosphere.

Explanation:

When the pressure is constant V/T is constant for a gas.

So 1000 / 293 = V / 283 (where the temperature is in degrees K.)

So the volume will decrease from 1000 cm^3.

Also as the temperature outside is colder the air in the balloon lost energy.
