Pressure versus density graph of an ideal gas is shown in the figure. Choose the correct statement.
A
During the process 
, work done by the gas is positive
, work done by the gas is positive B
During the process 
, work done by the gas is negative
, work done by the gas is negative C
During the process 
, internal energy of the gas is increasing
, internal energy of the gas is increasing D
During the process 
, internal energy is constant.
, internal energy is constant.
Text Solution
Verified by ExpertsThe correct answer is:
D
During 
and 
is constant. Therefore, work done is zero. During 
, i.e., 
and hence, 
is constant.
