 Physics 1B - Reading Quiz #2
1. A solid and a gas have similar molecular weights. The specific heat of the solid will tend to be
• A. less than that of the gas, because the gas molecules are not bound by intermolecular bonds.
• B. the same as that of the gas.
• C. greater than that of the gas because it takes heat to break the intermolecular bonds.
• D. greater than that of the gas because the solid has more ways of storing internal energy.
• E. unknown because it will depend most strongly on the atoms making up the molecules.

• A. increase in temperature significantly.
• B. increase the rate of vaporization significantly.
• C. decrease the rate of evaporation slightly.
• D. increase the temperature and decrease the rate of vaporization.
• E. increase the temperature and increase the rate of vaporization. freeze.
