You want to quickly set up a temporary water bath in your lab with a volume of 10.0 L and a temperature of 37.0°C. You only have hot water from your hot water faucet (temperature = 55.0°C) and cold water from your cold water faucet (temperature = 22.0°C). What volume of hot water (in liters) must you mix with cold water to get 10.0 L of 37.0°C water? Assume the specific heat of the water is 4.184 J/g･K and that the water has a density of 1.00 g/mL.

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...
