Question

Pressure-volume $(PV)$ work done by an ideal gaseous system at constant volume is (where $E$ is internal energy of the system

• A. $-?P/P$
• B. Zero
• C. $-V?P$
• D. $-?E$

Answer 1

Answer: (B)

Zero

Answer 2

From first law of thermodynamics $\Delta E=q+W$ where, work do net $(W)=p \Delta V$ $=p \times V$ $=0 (\because \Delta V=0)$
