The 
diagram shown below indicates two paths along which a sample of gas can be taken from state 
to state 
. The energy equal to 
in the form of heat is required to be transferred, if the Path-I is chosen. How much energy in the form of heat should be transferred, if Path-2 is chosen?
Text Solution
Verified by ExpertsThe correct answer is:
A
Work done in path 1
Area under 
From first law of thermodynamics,
Given, 
will be same for path 
path 2
Consider path 2
Also, work done for process 2 is
area under process 2
