Assertion : In an isothemal expansion the gas absorbs heat and does work while in an gas by the enviroment and heat is relaeased.
Reason: In an isothermal process there is no change in internal energy of an ideal gas.
A. If both assetion and reason are true and reaasons is the correct expanation of assetion
B. If both assetion and reason are tur but reason is not the correct explanation of assetion
C. If assertion is true but reason is false
D. If both assertion and reason are false.
