A 100 gram copper ball is dropped into a large container of liquid nitrogen until the nitrogen stops bubbling. Then the copper ball is taken out of the liquid nitrogen and placed in a glass of room temperature (25 degrees C) water. If there was 0.3 kg of water in the glass, isolated from the environment, what will be the eventual equilibrium temperature of the ball and water? Build an energy interaction diagram.
