Question
An ideal gas expands in such a way that PV2 = constant throughout the process. Select correct alternative
Options
A.This expansion is not possible without heating
B.This expansion is not possible without cooling
C.Internal energy remains constant in this expansion
D.Internal energy increases in the expansion
Solution
PV = nRT & PV2 = constant ⇒ V ∝ 
⇒ gas can expand only it it cods
As temperature decreases during expansion so internal energy will decrease will decrease.
⇒ gas can expand only it it codsAs temperature decreases during expansion so internal energy will decrease will decrease.
