Problem 17: Two amounts of salt water at different temperatures are brought into thermal contact with each other and mixed thoroughly. The first amount of water has mass m1 = 0.352 kg and its initial temperature is T1 = 7.21 °C. The second has a mass of m2 = 0.873 kg and an initial temperature of T2 = 34 °C. Assume that the system is isolated. Let the specific heat of the water at this salinity to be CW = 0.89 kcal / kg / K.Part (b) Find an expression for the final temperature of the water after thermal equilibrium has been reached.

Question

Problem 17: Two amounts of salt water at different temperatures are brought into thermal contact with each other and mixed thoroughly. The first amount of water has mass m₁ = 0.352 kg and its initial temperature is T₁ = 7.21 °C. The second has a mass of m₂ = 0.873 kg and an initial temperature of T₂ = 34 °C. Assume that the system is isolated. Let the specific heat of the water at this salinity to be C_W = 0.89 kcal / kg / K.

Part (b) Find an expression for the final temperature of the water after thermal equilibrium has been reached.
