Teaching DSSSB PGT Mock Test 2025 Thermodynamics Ideal and Real Gases Internal Energy and Enthalpy of a Perfect Gas
A system goes from A to B via two processes I and II as shown in figure. If ΔU1 and ΔU2 are the changes in internal energies in the processes I and II respectively, then the relation between ΔU1 and ΔU2 is
1
ΔU1 = ΔU2
2
ΔU2 < ΔU1
3
ΔU2 > ΔU1
4
