Question 395: Thermodynamics & KTG

Question

The internal energy (U), pressure (P) and volume (V) of an ideal gas are related as U $$=$$ 3PV + 4. The gas is :

Accepted Answer

U = 3PV + 4
$$ \Rightarrow $$ $${{nf} \over 2}$$RT = 3PV + 4
$$ \Rightarrow $$ $${{f} \over 2}$$PV = 3PV + 4
$$ \Rightarrow $$ f = 6 + $${8 \over {PV}}$$
Since degree of freedom is more than 6 therefore gas is polyatomic.

Answer

either monoatomic or diatomic.

Answer

monoatomic only.

Answer

polyatomic only.

Answer

diatomic only.
