a 0.5 kg block of aluminum is heated to 200 degrees C. The block is then quickly placed in an air insulated tub of cold water at 0 degrees C and sealed. At equillibrium, the temperature of the water and block are measured to be 20 degrees C. If the original experiment is repeated with a 1.0 kg aluminum block, what is the final temperature of the water and block? a)less than 20 C b)20 C c) more than 20 C.
