Four students are asked to state and explain the relative magnitudes of the thermal expansion of solids and gases. Which student is correct?
Gases expand more than solids because the molecules in a gas are in random motion.
Gases expand more than solids because the attractive forces between molecules are much weaker in gases.
Solids expand more than gases because the molecules are closer together in solids.
Solids expand more than gases because the molecules in a solid are in a regular pattern.
