JEE Main
JEE Main 2022
Thermodynamics
A
$\Delta H =\Delta U - P \Delta V$
56%
B
$\Delta U = q + W$
9%
C
$\Delta S_{\text {sys }}+\Delta S_{\text {surr }} \geq 0$
25%
D
$\Delta G =\Delta H - T \Delta S$
10%
Solution:
If $U + Pv$ (By definition)
$\Delta 14=\Delta U +\Delta(\text{Pr})$ at constant pressure
$\Delta H =\Delta U + P \Delta V$
