      In a gas, molecules move in and out of the liquid phase, with an energy cost. The expansion of a gas is free in the sense that the pressure remains constant. The amount of energy needed to expand a gas is called the heat capacity.

      Free expansion of gases is one type of fluid flow and it occurs when there is no work done on or by fluids in contact with one another. This happens when there is no friction between them and they are not moving. Free expansion always leads to an increase in temperature because energy must be put into the system for it to happen, otherwise it would stop due to friction or some other force acting on the fluids (e.g., gravity). It occurs naturally as heat moves from warmer to colder parts of a system and it can also occur inside bodies by absorbing

      Free expansion of a gas is a process in which the molecules of a gas are dispersed into its surroundings. When they are fully extended, they can no longer absorb any additional gas molecules and the pressure of the gas will decrease.

      A free expansion of a gas is characterized by a decrease in pressure. This is because most gases have low density and high molecular mobility, which allows them to diffuse into their surroundings easily.

      In real life, this process is seen when substances such as oxygen are introduced to an environment with underpressurized tanks or balloons that have been punctured.
