) A solid gas cylinder containing methane (CH4) has a volume of 32 m3. The cylinder is situated outdoors in Burnaby, B.C. and, during a period of time, the average atmospheric temperature was 65 "F while the gauge read 200 kPa. One day an accident occurs and there is small fire near the cylinder and its temperature rises to152 "F. a. How much total heat has been transferred (you must specify if the heat is added-to or removed-from the cylinder)? b. How much total work has been done (you must specify if the work is added-to or removed-from the cylinder?? What is the total change in enthalpy?
