Question

A sample of gas is filled in a closed vessel, if temperature of gas is increased by $2^{\circ }K$ and pressure by $0.2$ %, then initial temperature of gas wil be

• A. $200K$
• B. $273K$
• C. $400K$
• D. $1000K$

Answer 1

The correct option is D $1000K$

By, $PV=nRT$
So, $V=\frac{nR{T}_1}{P_1}=\frac{nR{T}_2}{P_2}\frac{T}{100}=\frac{T+2}{100.2}$
$100.2T=100T+200$
$T=1000K$
