As the pressure increases in an LP container, what also happens?

When pressure increases in a liquefied petroleum (LP) gas container, the liquid volume indeed expands. This relationship is rooted in the principles of gas behavior, particularly as described by the Ideal Gas Law and the characteristics of gases under varying pressures and temperatures.

As the pressure within the container rises, it forces the liquid gas to become more compressed. In a closed system, like an LP gas container, this increase in pressure effectively results in a greater density of the liquid phase, leading to an expansion of the liquid volume to fill the available space. With higher pressure, more gas molecules are forced into the liquid state, but the overall liquid volume can change based on the system's conditions.

It's important to note that while various other factors may seem relevant—such as temperature, which generally increases with pressure due to the compression, or that a drop in pressure would lead to decreased gas volume—it is the expansion of liquid volume characteristic of LP gases subjected to increased pressure that directly correlates with this question's focus.
