What will happen to the volume of a gas in a closed container if you increase the external pressure when the temperature remains constant?
If the container is closed, as the problem states, increasing the pressure on the outside of the container will not have an effect on the gas inside as long as the container stays intact. Or perhaps Ive misinterpreted the problem.
As pressure goes up and temperature is held constant, the volume of a gas decreases.
