The absolute temperature of a gas is increased 3 times. What will be the incraese in rms velocity of the gas molecule?

Text Solution

Verified by Experts

The relation between r.m.s. velocity and absolute temperature of a gas is `C prop sqrt(T)`
Therefore , the r.m.s. velocity becomes `sqrt(3)C`.
Hence, increase in r.m.s. velocity
`=sqrt(3)C - C = 0.732 C = 73.2%`.
