Question

A system goes from A to B via two processes I and II as shown in figure . if ∆U₁ and ∆U₂ are the changes in internal energies in the process I and II respectively , then [AIEEE 2005]
(a) ∆U₁ = ΔU₂
(b) relation between ΔU₁ and ΔU₂ cannot be determined
(c) ΔU₂> ΔU₁
(d) ΔU₂< ΔU₁ ​

Answer 1

Answer:

Au

Explanation:

• relation between cannot be determine

Answer 2

Answer:

Internal Energy (U) is a state function. It's value depends only on the initial and final positions.

Change in internal energy do not depend upon the path followed by the process. It only depends on initial and final states i.e

ΔU1 = ΔU2.
