Calculate the change in entropy (in J/K ) when a 73.0g of water is heated from 23.4C to 92.5C at 1atm. (The specific heat is 4.184 J/(gK)) Notice that entropy and heat capacity have the same units. Answer: In the previous problem the gas is heated at constant pressure. This means that as the gas warms, it also expands. Would the change in entropy be the same, if the gas were heated at constant volume and then allowed to expand such that the final temperature, pressure, and volume were the same as the constant pressure case? Select one: a. YES b. NO c. MAYBE (It depends on the details of how it is done.)
