23M.1A.SL.TZ1.13
Two blocks X and Y at different temperatures are placed in thermal contact with each other until they reach thermal equilibrium. Block X and block Y are of the same material. The mass of block Y is half that of block X. The change in temperature of block X has a magnitude ΔT and the change in internal energy of block X has a magnitude ΔU. What is the change in magnitude of temperature of block Y and the change in magnitude of internal energy of block Y?
