An ice tray contains 750g of liquid water at 0C. A) Calculate the entropy change of water as it is cooled slowly from 30C to 0C. B) Calculate the change in entropy of the water as it freezes slowly and completely at 0C. The heat of fusion of water is 3.33*10^5 j/kg
What is the change in entropy of 0.97 mol of liquid water at 0.0 degree C that freezes to ice at 0.0 degree C? J/K
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.
Calculate the change in entropy when 65 g of ice at 0 °C melts to water at 0 °C? The heat of fusion is 3.34x10 J/kg.

Calculate the change in entropy that occurs when 18.02 g of ice at –17.5°C is placed in 90.08 g of water at 100.0°C in a perfectly insulated vessel. Assume that the molar heat capacities for H2O(s) and H2O(l) are 37.5 J K^-1 mol^-1 and 75.3 J K^-1 mol^-1, respectively, and the molar enthalpy of fusion for ice is 6.01 kJ/mol. Change in entropy = ______J/K
7) Calculate the entropy change when 1 mole of water is warmed from 0°C to 25°C (specific heat capacity of water = 4.184 J/gK) (remember to break it to into steps-ice melting and then the liquid water going from 0°C to 25°C)
Please help 1. Calculate the increase of entropy (in J/K) when 42 g of ice melts at 0 ºC and 1 atm. (The heat of fusion for ice is 6,000 J/mol.) 2. Calculate the change in entropy (in J/K) when a 34.0 g of water is heated from 12.4 ºC to 70.5 ºC at 1 atm. (The specific heat is 4.184 J/(g-K).) Notice that entropy and heat capacity have the same units.
What is the entropy change of the universe (in J K-1)when 2.00 mol of liquid water at 0 °C freezes in a freezer compartment whose temperature is -15 °C? Assume the freezer is a perfect insulator. (AHfus = 6.01 kJ mol-1 for water) Select one: O a. +90.6 O b. +46.6 C. -2.6 O d. -44.0 o e. +2.6
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?
