100 moles of an ideal (take y = 1.5) gas undergo a cycle which consists of three processes. Process 1 -> 2 is an isochoric (constant volume) process, process 2 -> 3 is an adiabatic process, and process 3 -> 1 is an isobaric process. (a) Find the total work (net work) done by the cycle given that P, = 3.0 x 10 Pa, P. = 2 24.0 x 10" Pa, P, = 3.0 x 10 Pa, V, = 0.90 m", and V, = 0.90 m . (b) Find the thermal efficiency of the cycle? (c) What would the efficiency be if this was a Carnot cycle?An ideal gas is enclosed within a container by a moveable piston. The initial pressure of the gas is 3.5 x 10 Pa. If the final temperature is 7 times the initial temperature and the final volume is 1/4 of its initial value, what will the final pressure of the gas be in Pa? Please round your answer to the nearest whole number (integer)
