The figure shows the P-V plot of an ideal gas taken through a cycle 
. The part 
is a semi-circle and 
is half of an ellipse. Then,
A
the process during the path 
is isothermal
is isothermal B
heat flows out of the gas during the path 
C
work done during the path 
is zero
is zero D
negative work is done by the gas in the cycle 
Text Solution
Verified by ExpertsThe correct answer is:
B
Process is not isothermal
Volume decreases and temperature decreases 
negative,
So, 
negative
Work done in process 
is positive
Cycle is clockwise, so work done by the gas is positive
