Physics Kinetic Theory of Gases JEE Main 2024

The total kinetic energy of 1 mole of oxygen at 27°C is [Use universal gas constant (R) = 8.31 J/mole K]

(A)6232.5 JCorrect
(B)5670.5 J
(C)5942.0 J
(D)6845.5 J

Answer: (A)

Solution

Oxygen is diatomic, so the total kinetic energy of one mole is (5/2)RT = 2.5 × 8.31 × 300 = 6232.5 J.
