Unformatted text preview: entrapped ideal gas is 0.15 m 3 . The piston and cylinder do not conduct heat, but heat can be added to the gas by a heating coil. The gas has an initial temperature of 298 K and enough heat is added to triple the volume. Calculate the amount of heat that must be added to accomplish this change, the final temperature of the gas, and the work the gas does against its surroundings. (8 pts) Given: C v = 21 J/mol*K for the ideal gas. 3. Sandler 3.10 (5 pts) 4. Steam at 150 bar and 700C is to undergo a Joule-Thomson expansion to atmospheric pressure. a) What will be the temperature of the steam after the expansion? (3 pts) b) What would be the downstream temperature if the steam were replaced by an ideal gas? (3 pts)...
