An aluminium plate and a glass plate are left in a room for a long time. Putting one ice cube on each plate, you notice that the ice melts faster on the aluminium plate. Why?
a) The ice is in thermal equilibrium with the glass plate, but not with the aluminium plate.
b) Aluminium conducts heat to the ice more rapidly than glass.
c) The aluminium plate holds more heat.
d) The aluminium plate is warmer.
