Answer to Question #349710 in General Chemistry for pitpit

Question

if the volume of confined gas is doubled while the temperature remains constant, what change would be observed in the pressure?

Answer 1

The volume of a gas in a closed container at constant temperature is directly proportional to its pressure:

$\cfrac {V}{V_0}=\cfrac {P}{P_0}$

According to the above, doubling the volume of gas also doubles the pressure because the gas is in a closed container.
