Some gases are stored at high enough pressures to force the gas back into a _____ state inside the container.

When a gas is stored under high pressure and at a temperature where condensation can occur, it can be forced into a liquid state inside the container. This is the idea behind liquefied gases: the gas is kept under enough pressure that the molecules come together into a liquid phase, with some vapor above it. In such cylinders, you typically have mostly liquid propane, chlorine, or similar liquefied gas, and as you release it, the liquid boils off to maintain the pressure and become gas again. The others describe a state or a property, not the actual phase the gas takes in the container, so they don’t fit as well.
