Which of the following statements correctly compares the efficiency of thermal energy transfer by molecular collisions in solids, liquids, and gases of the same substance at the same temperature?
(a) Liquids transfer thermal energy most rapidly because their particles are mobile and closely spaced, whereas solids and gases are less effective.
(b) Gases transfer thermal energy most rapidly because their particles move fastest, while solids transfer energy slowest due to restricted motion.
(c) Solids transfer thermal energy most rapidly because their particles are closest together, whereas gases transfer energy slowest because their particles are far apart.
(d) All three states transfer thermal energy at the same rate when at the same temperature because they have the same average kinetic energy.
