Problem
You put two identical ice cubes on plates of different materials. One cube is put on an aluminum plate, and the other on a glass plate. Both plates have been in the room for a long time prior to the experiment. You notice that the ice melts faster on the metal plate. Why?
a) The ice is in thermal equilibrium with the plastic plate, but not with the metal plate.
b) The metal plate conducts heat to the ice more rapidly than the plastic plate.
c) The metal plate holds more heat than the plastic plate.
d) The metal plate was warmer than the plastic plate initially.
