If a 20 gram piece of copper at 50oC touches a 10 gram piece of copper at 90oC, in which direction will heat flow? Estimate the final temperature once both pieces of copper reach thermal equilibrium and explain your estimate. a)
the heat flows from the 10 g piece to the 20 gram piece and final temperature is about 70oC because they are both made out of copper
b)
he heat flows from the 20 g piece to the 10 gram piece and final temperature is about 50oC because the hot piece has lower mass
