Question 403: Thermodynamics & KTG

Question

An ideal gas occupies a volume of 2m
3
at a pressure of 3 $ 	imes $ 10
6
Pa. The energy of the gas is :

Accepted Answer

Energy = ${1 \over 2}$ nRT = ${f \over 2}$PV
= ${f \over 2}$ (3 $ 	imes $ 10
6
) (2)
= f $ 	imes $ 3 $ 	imes $ 10

Considering gas is monoatomic i.e. f = 3
E. = 9 $ 	imes $ 10
