`6xx10^(22)` gas molecules each of mass `10^(-24)kg` are taken in a vessel of 10 litre. What is the pressure exerted by gas molecules ? The root mean square speed of gas molecules is `100 m//s`.

Options

A. 298 K
B. 25 K
C. 250 K
D. 2500 K

Answer

c

Explanation

(c) `1000=sqrt((3RT)/(M)),10^(3)=[(3xx8.314xxT)/(10^(-26)xx6xx10^(23))]^(1//2)`
` T=(10^(6)xx10^(-26)xx6xx10^(23))/(3xx8)=250K`
