One mole of helium is adiabatically expanded from its initial state $$({{P}_{i}},{{V}_{i}},{{T}_{i}})$$ to its final state $$({{P}_{f}},{{V}_{f}},{{T}_{f}})$$. The decrease in the internal energy associated with this expansion is equal to [SCRA 1994; BHU 2002]

If assertion is true but reason is false.

TuteeHUB · Answer

$$({{C}_{P}}-{{C}_{V}})({{T}_{i}}-{{T}_{f}})$$

1.	One mole of helium is adiabatically expanded from its initial state \[({{P}_{i}},{{V}_{i}},{{T}_{i}})\] to its final state \[({{P}_{f}},{{V}_{f}},{{T}_{f}})\]. The decrease in the internal energy associated with this expansion is equal to [SCRA 1994; BHU 2002]
A.	\[{{C}_{V}}({{T}_{i}}-{{T}_{f}})\]
B.	\[{{C}_{P}}({{T}_{i}}-{{T}_{f}})\]
C.	If assertion is true but reason is false.
D.	\[({{C}_{P}}-{{C}_{V}})({{T}_{i}}-{{T}_{f}})\]
Answer» B. \[{{C}_{P}}({{T}_{i}}-{{T}_{f}})\]
