For an ideal gas four processes are marked as 1,2,3 and 4 on P-V diagram as shown in figure. The amount of heat supplied to the gas in the process 1,2,3 and 4 are `Q_1, Q_2, Q_3` and `Q_4` respectively, then correct order of heat supplied to the gas is : [AB is process-1, AC is process-2, AD is adiabatic process-3 and AE is process-4]

Options

A. `Q_(1) gt Q_(2) gt Q_(3) gt Q_(4)`
B. `Q_(1) lt Q_(2) lt Q_(3) lt Q_(4)`
C. `Q_(1) gt Q_(2) gt Q_(4) gt Q_(3)`
D. `Q_(1) gt Q_(4) gt Q_(2) gt Q_(3)`

Answer

A

Explanation

In process-1 heat supplied =area under AB curve `+n xxC_(v)xx100`.....(isobaric process)
In process -2 heat supplied =area under AC curve ....(isothermal process)
In process -3 heat supplied =0 ....(adiabatic process)
In process-4 heat supplied =`n xx C_(v) (T-600)`=negative .......(isochoric process)
