What occurs at thermal equilibrium?

Heat flows from the higher-temperature substance to the lower-temperature substance.
Heat flows from the lower-temperature substance to the higher-temperature substance.
Heat does not flow because both substances are at the same temperature.

Mario and Patience are making cookies. They are ready to drop balls of dough on baking sheets. They have baking sheets made of treated glass, aluminum, stainless steel, and copper. The specific heats of these substances are:
Treated glass = 0.75 J/g • °C
Aluminum = 0.90 J/g • °C
Stainless steel = 0.50 J/g • °C
Copper = 0.39 J/g • °C

Based on the specific heat values, which sheet is going to warm up the quickest, and, therefore, bake the cookies the fastest?
copper
