A bathtub holds 135 L of hot water at 41.0°C. Cold water at 13.0°C is added to the bathtub until the water reaches a final equilibrium temperature of 38.5°C. Assuming only a negligible amount of energy is exchanged between the water and its environment during this time, determine the volume in liters (L) of the added cold water. The specific heat of water is 4.19 ✕ 103 J/(kg · °C) and its density is ρ = 1.00 kg/L. What is...
