Question

A monoatomic gas of mass 4 . 0 u is kept in an insulated container. The container is moving with velocity 30 m s - 1 . If the container is suddenly stopped then a change in temperature of the gas ( R = gas constant) is x 3 R . Value of x is,

TestHub · Accepted Answer

Given that mass of gas is 4 u hence its molar mass M is 4 g mol - 1 ∴ 1 2 m v 2 = n C v Δ T ⇒ 1 2 m × 30 2 = m M × 3 R 2 × Δ T ∴ Δ T = 3600 3 R
