A gas at the temperature 250 K is contained in a closed vessel. If the gas is heated through 1K, then the percentage increase in its pressure will beA. `0.4%`B. `0.2%`C. `0.1%`D. `0.8%`

Answer» Correct Answer - A
`p prop T rArr(p_(1))/(p_(2))=(T_(1))/(T_(2)) rArr(p_(2)-p_(1))/(p_(1))=(T_(2)-T_(1))/(T_(1))`
`rArr" "((Deltap)/(p))%=((251-250)/(250))xx100=0.4%`
