Adding Ice to Water An insulated beaker with negligible mass contains liquid water with a mass of 0.305 kg and a temperature of 62.4 degree C Part A How much ice at a temperature of -20.4 degree C must be dropped into the water so that the final temperature of the system will be 27.0 degree C ? Take the specific heat of liquid water to be 4190 J/kg K the specific heat of ice to be 2100 J/kg .K...
Calculate the ideal power in kW to make 1 Ton (=1000 kg) of ice at 0 deg.C per hour from water at 20 deg.C. Surroundings at 20 deg.C. Use the expression for Wideal to calculate the power. The total enthalpy change of the water = [(enthalpy change of the water cooled from 20 to 0 deg.C) + (enthalpy change of water to ice at 0 deg.C, this is the heat of fusion of water)]. The total entropy...

Calculate the entropy change for the hypothetical process in which 0.5 g of ice at 0°C melts to water at 0°C and 0.5 g water at -10°C freezes to ice at -10°C. Assume ΔH-fusion is 80 cal/g, independent of temperature. Please show all work, include explanations and formulas that were used.
An insulated Thermos contains 135 g of water at 86.5 ˚C. You put in a 7.06 g ice cube at 0.00 ˚C to form a system of ice + original water. The specific heat of liquid water is 4190 J/kg•K; and the heat of fusion of water is 333 kJ/kg. What is the net entropy change of the system from then until the system reaches the final (equilibrium) temperature?
