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!!!
