Can Crusher Lab We know from class that a substance’s temperature increases directionally proportional to the substance’s volume when at a constant pressure. We also know that when the volume increases, it is inversely proportional to its pressure when at a constant temperature. Nature likes to be stable, or in balance with itself. To achieve this state of equilibrium, nature will transfer energy from the object with the most energy to the object with the least. For example, if you put an ice cube in a room that is 80°F, the ice cube will melt. Heat from the room goes to the ice cube. If you put liquid water into a room that is 30°F (below freezing), the liquid will freeze. The cold room absorbs any heat from the water until the water freezes.
