Question

Problem 2: (Callen Problem 4.5-14) 4.5-14. If the temperature of the atmosphere is 5°C on a winter day and if 1 kg of water at 90°C is available, how much work can be obtained as the water is cooled to the ambient temperature? Assume that the volume of the water is constant, and assume that the molar heat capacity at constant volume is 75 J/mole K and is independent of temperature. Answer: 45 \times 10^3 J

4.5-14. If the temperature of the atmosphere is 5°C on a winter day and if 1 kg of
water at 90°C is available, how much work can be obtained as the water is cooled
to the ambient temperature? Assume that the volume of the water is constant, and
assume that the molar heat capacity at constant volume is 75 J/mole K and is
independent of temperature.
Answer:
45 \times 10^3 J

Step 1

The initial temperature of the water is 90°C and the final temperature is 5°C. Therefore, the change in temperature is 90°C - 5°C = 85°C. Show more…
