At a given temperature the root mean square velocities of oxygen and hydrogen molecules are in the ratio
Options
(a) (16:1)
(b) (1:16)
(c) (4:1)
(d) (1:4)
Correct Answer:
(1:4)
Explanation:
v(rms) = √(3RT / M)
Where M is the molecular mass
Since the temperature remains the same
v(rms) ∝ 1 / √M
[v(rms)]o₂ / [v(rms)]ʜ₂ = √(Mʜ₂ / Mo₂) = √(2 / 32) = 1 / 4
Related Questions: - A radioactive nucleus of mass M emits a photon of frequency v and the nucleus recoils.
- Two sound waves of wavelengths 5m and 6m formed 30 beats in 3 seconds
- The temperature coefficient of the resistance of a wire is 0.00125 per ⁰C.
- The current through an inductor changes from 3 A to 2 A is 1 m/s. If induced e.m.f.
- Photon of frequency ν has a momentum associated with it. If c is the velocity
