1. The ideal gas law (PV=nRT) provides relationships among pressure, volume, amount, and temperature of a gas inside a container. If the Kelvin temperature in a container is doubled, which of the following changes may occur?
A. .One-half of the amount of gas is removed from the container.
B. The volume is doubled and the pressure is halved while no more gas is added to the container.
C. The volume is halved and the pressure is doubled while no more gas is added to the container.
D. The volume and the pressure are both doubled while no more gas is added to the container.
E. The volume and the pressure are both halved while no more gas is added to the container.
