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
4. The heat of vaporization (AH) of water at 100C is 40.6 k]/mol and when 1mol of water is vaporized at 100C and 1 atm pressure the volume increase is 30.19dm3. Calculate the work done by the system, the change in internal energy Δυ, the change in Gibbs energy ΔG and the entropy change AS.
Question 26 The boiling point of water is 100C and 212F. The freezing point of water is 0C and 32F. Can you write an equation for the conversion of the temperature from C to F using this information? (Hint, two points can be expressed on a graph, then one needs to determine the slope = (rise/run) and the Y intercept to form an equation to express one variable in terms of the other) a) What would be the Y intercept...
Water and ice are mixed together in a glass and have come to equilibrium with each other. The glass is in a warm room. In a period of S minutes 0.024 kg of the ice melts. The latent heat for the ice-water transition is L 3.3 x 10 What is the change in entropy of the water-ice mixture during this process? Answer in . kg Answer: Save response
