What is the change in entropy of 1,000 kg of ice at 0.0˚ when it melts and 15. What is the change in entropy of 1,000 kg of ice at 0.0˚ when it melts and becomes steam at 100.0˚C
a. What is the change in entropy of 1,000 kg of ice at 0.0˚ when it melts and 15. What is the change in entropy of 1,000 kg of ice at 0.0˚ when it melts and becomes steam at 100.0˚C?
b. An ideal engine has an efficiency of 28% when the temperature of its hot 4. An ideal engine has an efficiency of 28% when the temperature of its hot reservoir is 120°C. What must be the reservoir's temperature if it is desired to reservoir is 120°C. What must be the reservoir's temperature if it is desired to increase the efficiency to 35%? Assume that the temperature of the cold increase the efficiency to 35%? Assume that the temperature of the cold reservoir is the same for both cases.
