What will happen to the volume if the temperature of the gas is increased?

The volume of the gas will increase as the temperature increases too, gas molecules become more energetic and have an increase in kinetic energy and move quickly. This includes the molecules spread out more and take up more space. The pressure around the molecules also changes, there is much more force put into the molecules and it needs larger environment so the pressure can return to a regular amount/value.

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.
