Question

Which relation is correct for isometric process

• A. $\Delta Q = \Delta U$
• B. $\Delta W = \Delta U$
• C. $\Delta Q = \Delta W$
• D. None of these

Answer 1

Answer: (A)

$\Delta Q = \Delta U$

Answer 2

For isochoric process$\Delta V = 0$

⇒ ∆W = 0

From FLOT $\Delta Q = \Delta U + \Delta W$

⇒$\Delta Q = \Delta U$
