Assuming that negligible heat is taken from the surroundings, the temperature of water in the tumbler becomes nearly $(L=80 \mathrm{cal} / \mathrm{g})$

146483 Two identical bodies are made of a material for which the heat capacity increases with temperature. One of these is at $100^{\circ} \mathrm{C}$, while the other one is at $0^{\circ} \mathrm{C}$. If the two bodies are brought into contact, then assuming no heat loss, the final common temperature is
