KE per unit volume is

E

. The pressure exerted by the gas is given by

View answer and explanation

Correct option: B

\frac{{2E}}{3}

Option B (

\frac{{2E}}{3}

) is correct because the pressure exerted by a gas is related to the kinetic energy per unit volume by the equation

P = \frac{2}{3}E

.

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
