In the process of taking a gas from state 'a' to state c along the curved path shown in the image. 85J of heat leaves the system and 55J of work is done on the system. a) determine the change in internal energy, Ea-Ec. b) when the gas is taken along the path cda, the work done by the gas is W=38J. How much heat Q is added to the gas in the process cda? c) if Pa= 2.2Pd, how much work is done by the gas in the process abc?. Ea-Eb=15

suppose the gas above is taken clockwise around the rectangular cycle shown in the image. Starting at b, then to a, to d, to c and returning to b. Using the values given in question 1 above d) describe each leg of the process and then calculate e) the net work during the cycle and f) the net heat during the cycle. g) what percentage of intake heat has turned into usable work i.e how efficient is this "rectangular" cycle ( give as a percentage)
