Root mean square velocity of a gas is x ms-1 at a pressure p atm and temperature T K. If pressure is made 2p under isothermal condition root mean square speed becomes​

Answer 1

Answer:

P= 1/3 dV² rms

P = 1/3 [n.M/V] V² rms

P= Pressure

d= density of gas

n= number of moles

M= Mass of gas

Vrms = root mean square velocity.

Root mean square velocity of a gas is xmS-¹

at a pressure P atm

If pressure is doubled, V

rms

will increase 4 times.

root mean square speed becomes 4X.
