Question:
This problem examines the effect of mixing water at two different temperatures and/or two different phases, such as dropping ice cubes into warm water. Assume that ΔHfus = 333.55 J/g, that CP for ice is constant at 2.11 J/g · K, and that CP for liquid water is constant at 4.19 J/g · K. For each the following cases, assume the mixing is adiabatic and carried out at atmospheric pressure. For each case, determine the temperature and phase of the water when the mixing is complete. If there are two phases in equilibrium, determine the mass of each phase.
A. 100 g of liquid water at 50°C is mixed with 50 g of liquid water at 08C.
B. 100 g of liquid water at 50°C is mixed with 50 g of ice at 08C.
C. 50 g of liquid water at 0°C is mixed with 50 g of ice at 0°C.
D. 50 g of liquid water at 20°C is mixed with 50 g of ice at –20°C.
