NEET Physics Thermodynamics Questions Solved


An ideal gas goes from state A to state B

via three different processes as indicated 

in the p-V diagram

If Q1, Q2, Q3 indicates the heat absorbed

by the gas along the three processes and 

U1, U2, U3 indicates the change in 

internal energy along the three processes

respectively, then

(a) Q1>Q2>Q3 and U1= U2= U3

(b) Q3>Q2>Q1 and U1= U2= U3

(c) Q1=Q2=Q3 and U1>U2>U3

(d) Q3>Q2>Q1 and U1>U2>U3
