Carbon dioxide (CO₂) fills a closed, rigid tank fitted with a paddle wheel, initially at 80°F, 50 lb/in2, and a volume of 2.0 ft³. The gas is stirred until its temperature is 500°F. During this process heat transfer from the gas to its surroundings occurs in an amount 2.6 Btu. Assume ideal gas behavior, but do not assume constant specific heats. Kinetic and potential energy effects can be ignored. Determine the mass of the carbon dioxide, in lb, and the work, in Btu. Step 1 Determine the mass of the carbon dioxide, in lb. m = i lb

9.16. One kind of thermodynamic diagram that is useful in engineering problems is the P–H diagram, in which the x-axis is molar enthalpy and the y-axis is pressure.(a) Several kinds of iso-lines can be drawn in such a diagram, including isotherms(constant temperature), isentrops (constant entropy), and isochores (constant molar volume). For each of these three cases, find expressions for the slope of these lines on a P–H diagram in terms of measurable properties.(b) Find expressions for these slopes for the ideal monatomic gas, in terms of T and P.
