Question

What is the ratio of the total energy of all the molecules of one mole of O 2 to the total energy of all the molecules of two moles of helium at the same temperature? (A) 1: 2 (B) 2: 1 (C) 2: 3 (D) 3: 2

(E1/E2)=(N × (3/2) k T/2 N × (3)2 k T) =(1/2)

Q. What is the ratio of the total energy of all the molecules of one mole of $O_{2}$ to the total energy of all the molecules of two moles of helium at the same temperature?

1 : 2

2 : 1

2 : 3

3 : 2

$\frac{E _{1}}{E _{2}} = \frac{N \times \frac{3}{2} k T}{2 N \times \frac{3}{2} k T}$
$= \frac{1}{2}$
