In our previous discussions, we discussed how phase changes (gas to liquid to solid, for example) can occur by manipulating the parameter of temperature. We defined temperature as the average kinetic energy of the particles, so when we raise or lower the temperature, we are adding or removing energy to the system, respectively. Gas Cool or compress Heat or reduce pressure Liquid Cool Heat Crystalline solid Based on your observations over the past two weeks, please explain why lowering the temperature can condense the helium gas into a liquid, a process by which the He atoms stick together?

Four liquids are described in the table below. Use the second column of the table to explain the order of their freezing points, and the third column to explain the order of their boiling points. For example, select '1' in the second column next to the liquid with the lowest freezing point. Select '2' in the second column next to the liquid with the next higher freezing point, and so on. In the third column, select '1' next to the liquid with the lowest boiling point, '2' next to the liquid with the next higher boiling point, and so on.
