Question

Out of the following gases under similar condition of temperature and pressure, the velocity of sound will be maximum in

• A. Hydrogen
• B. Nitrogen
• C. Oxygen
• D. Chlorine

Answer 1

Answer: (A)

Hydrogen

Answer 2

Velocity of te4h sound in gas

$v = \sqrt{\frac{\gamma RT}{M}}$

Where the symbols have their usual meanings.

All the given gases are diatomic and are at same temperature,

$\therefore v \propto \frac{1}{\sqrt{M}}$
