Does the expansion of air cause its temperature to increase or decrease? Why?
Expansion decreases the temperature of air. As air rises in the atmosphere the surrounding air pressure decreases allowing for the air to expand. Because there is no other energy source, the air molecules use their own energy to spread out. This energy loss causes a reduction in molecular speed and, therefore, air temperature as well.
