A vessel has

6 \mathrm{~g}

of hydrogen at pressure

P

and temperature

500 \mathrm{~K}

. A small hole is made in it so that hydrogen leaks out. How much hydrogen leaks out if the final pressure is

\frac{P}{3}

and temperature falls to 300 K?

View answer and explanation

Correct option: C

2.66 g

Option C (2.66 g) is correct because the mass of gas remaining is calculated using the ideal gas law, and the difference between the initial and final mass gives the mass leaked out.

Assertion: The pressure exerted by an enclosed ideal gas does not depend on the shape of the container.
Reason: The pressure of an ideal gas depends on the number moles, temperature and volume of the enclosed If

c_s

is the velocity of sound in air and

c

is the rms velocity, then Four particles have velocities

1,0,2,3 \mathrm{~m} / \mathrm{s}
