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

Question

Accepted Answer

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

Answer

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

Answer
