Question

At constant pressure, how are the temperature and volume of a gas related?

A They are inversely proportional.

B They are directly proportional.

C They are constant.

D They are indirectly proportional.

Answer 1

The volume of a given gas sample is directly proportional to its absolute temperature at constant pressure (Charles's law). The volume of a given amount of gas is inversely proportional to its pressure when temperature is held constant (Boyle's law).
