A gas in a vessel is at the pressure P0. If the masses of all the molecules be made half and their speed be made double, then the resultant pressure will be –

A

4P0

B

2P0

C

P0

D

P0/2

Answer

2P0

Explanation

Solution

P = m.vrms23v\frac{m.v_{rms}^{2}}{3v} P=2P0\begin{matrix} \therefore P' = 2P_{0} \end{matrix}
