An ideal gas with a known gamma , completes a cycle consisting of two isotherms and two isobars. The isothermal processes are executed at temperatures T and T' (lt T) and isobaric processes are completed at pressures P_(0) and eP_(0) [e = base of natural logarithm]. Find the efficiency of the cycle.

One mole of an ideal gas at temperature T was cooled isochorically till the gas pressure fell from P to (P)/(n) . Then, by an isobaric process, the gas was restored to the initial temperature. The net amount of heat absorbed by the gas in the process is

One mole of idea monoatomic gas at 300 K undergoes an adiabatic irrersible process due to which its interhnal energy decreases by 150 calories. If the process is carried out isobarically to obtain same work then the enthalpy change of the isobaric process is :

A gas undergoes cyclic process 1-2-3-4-1 in which 1-2 and 3-4 are adiabatic process 2-3 and 4-1 are isobaric process. If (P_(2))/(P_(1))=k then what will be the efficiency of cycle in terms of k and gamma where gamma=C_(p)//C_(v) .

An ideal gas expands from V to 2V in 4 separate processes. Where process 1 is isothermal process 2 is adiabatic, process 3 is free expansion and process 4 is isobaric. If E_(1),E_(2),E_(3) and E_(4) are the changes in average kinetic energy of the molecules in the isothermal, adiabatic free expansion and isobaric process respectively then choose the correct options.

A thermodynamic system is taken from an original state D to an intermediate state E by the linear process shown in (figure) Its volume is then reduced to the original value from E to D via F by an isobaric process. Calculate the total work done by the gas from D to E to F to D.

A cylinder fitted with a piston contains an ideal monoatomic gas at a temperature of 400K . The piston is held fixed while heat DeltaQ is given to the gas, it is found the temperature of the gas has increased by 20K . In an isobaric process the same DeltaQ heat is supplied slowely to it. Find the change in temperature in the second process?
