more thermodynamic questions...desperate for help!!! 2) An engine with an output of 200W has an efficiency of 30%. it runs at 10cycles/sec -how much work is done in each cycle? -how much heat is absorbed and how much is ejected in each cycle? 3) an ideal monatomic gas is expanded from initial volum V1=1L, P1=2am and T1=300K to a volume V2=2L and P2=1atm. the expansion is performed along a straight line in the PV diagram. it is then re-compressed isothermally to its original value -find the funciton P(V)describing the expansion -find the function T(V) during the expansion -at which volume is the temperature a maximum Tmax and what is the vlume Vm @ this maximum temperature, Tmax? -what are these values for the final part of the expansion Vm to V2? -find efficiency 4) a horizontal insulated cylinder contains a frictionless nonconducting piston. On each side of the piston are 54L of monatomic gas gamma=5/3 at 1am and 273K. Heat is slowly applied to the gas on left side until the pison has compressed the gas on the right side to 7.59 atm. -how much work is done on the gas on the right? -what is the temperature on the right side and what is it on the left side? PLEASE HELP!!!!! THANKS!!!
