Question

A monoatomic gas of n-moles is heated from temperature T₁ to T₂ under two different conditions (i) at constant volume and (ii) at constant pressure. The change in internal energy of the gas is

• A. More for (i)
• B. More for (ii)
• C. Same in both cases
• D. Independent of number of moles

Answer 1

Answer: (C)

Same in both cases

Answer 2

Change in internal energy $\Delta U = \mu C_{V}\Delta T$ it doesn’t depend upon type of process. Actually it is a state function
