Calculate the temperature at which rms velocity of a gas is half it's value at `0^@C` , pressure remaining constant

Text Solution

Verified by Experts

Here, `T_1=0^@C = (0+273)K=273K`
`T_2=? V_2=1/2V_1`
As `V_2/V_1=sqrt((T_2)/T_1)=1/2`
`T_2=sqrt(T_1/4)=273/4=68.25A`
`=(68.25-273)^@C`
`=-(204.75)^@C`
