The ratio of rms speed of an ideal gas molecules at pressure

p

to that at pressure

2 p

View answer and explanation

Correct option: C

1: \sqrt{2}

Option C (

1: \sqrt{2}

) is correct because the rms speed is inversely proportional to the square root of the density, and density is proportional to pressure at constant temperature.

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
