Q24. A hot lead ball, mass = 0.30 kg, is dropped into an ideal calorimeter (no heat lost to the surroundings) containing 0.50 kg of water initially at 20.0 °C. The final equilibrium temperature of the lead ball and the water is 21.3 °C. Find the initial temperature of the lead ball. The specific heat capacity of lead is 128 J/(kg·C°); and the specific heat capacity of water is 4186 J/(kg·C°).
