Question

A gas in a cylinder is at pressure P. If
the masses of all the molecules are made
one third of their original value and
their speeds are doubled, then find the
resultant pressure.​

Answer 1

Answer:

2P

Pressure of gas = P

Mass of molecules is halved and speed is doubled, Thus,

P = 1/3 mn / V . V²ᵣₘₛ

When mass is halved and speed is doubled then

Resultant pressure = Pᵗ = P2/P1 = m2/m1×(v2/v1)²

= (m1/2)/2×(2v1/v1)²

= 2 - P2 = 2P1 = 2P0
