Question

An ideal gas is taken from state A to state B follow three different paths as shown in p – V diagram. Which one of the following is true?

• A. Work done is maximum along AB
• B. Work done is minimum along AB
• C. Work done along ACB = work done along ADB
• D. Work done along ADB is minimum

Answer 1

The correct option is D Work done along ADB is minimum

$W=\int pdV=$ area under the $p-V$ curve
= minimum along $ADB$
