Old EXAM Problem. You feed a liquid into a very large tank that has top (i.e. like a piston) that can adjust to keep the tank at a fixed pressure. The tank has an initial volume of 50m3. If the system pressure is 1.5 bar and 325K, what will be the final temperature and final volume in the tank if you add 1000kJ of heat? Assume the following: V=2.5103K1KT=4.5105bar1V=25cm3/molCv=5J/molK (a) Determine the amount of moles in your system. (b) Write out the 1st Law of Thermodynamics equation you will use to solve this problem. Note: You don't have to start from the general balance - you just have to write out the final expression you will use with the relevant terms. (c) Determine the final temperature in the tank. (d) Determine the final volume of the tank
