JEE MainPhysicsModerateThermodynamics

When a gas in a vessel expands, its internal energy decreases.
The process involved is

Show answer and solution
Internal energy decreases ⇒\Rightarrow temperature drops.
Expansion
⇒\Rightarrow not isochoric
 Cooling 
⇒\Rightarrow not isothermal
In isobaric process,
V∝T⇒ V \propto T \Rightarrow \ expansion raisestemp.
