A gas in a closed container undergoes the cycle ABCA as shown in the figure. The net heat absorbed by the gas after it has completed 10 cycles is
Options
- A-1.5 ~kJ
- B+1.5 ~kJ
- C+2.25 ~kJ
- D-2.25 ~kJ
Correct answer
A. -1.5 ~kJ
Step-by-step solution
Q = W [ process is cyclic ]=- [ 1 2 15 20 ] 10 [ no. of cycles =10]=-1500 ~J As cycle is anti-clock wise. So W is -ve therefore, Q is -ve.
