For the indicator diagram given below, which of the following is not correct?

A thermodynamic system undergoes cyclic process ABCDA as shown in figure. The work done by the system in the cycle is

(1) ρ_oV_o 

(2) 2ρ_oV_o

(3) ρ_oV_o/2

(4)zero

If Q, E and W denote respectively the heat added, change in internal energy and the work done in a closed cyclic process, then

(1) W=0                                 

(2) Q=W=0

(3) E=0                                   

(4) Q=0

In a cyclic process, the internal energy of the gas:

A thermodynamic system is taken through the cycle PQRSP process. The net work done by the system is -

(1) 20 J

(2) – 20 J

(3) 400 J

(4) – 374 J

An ideal gas is taken through the cycle A → B → C → A, as shown in the figure. If the net heat supplied to the gas in the cycle is 5 J, the work done by the gas in the process C → A is

(3) – 15 J

(4) – 20 J

In the following indicator diagram, the net amount of work done will be
