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 be

Options

A. `0.4%`
B. `0.2%`
C. `0.1%`
D. `0.8%`

Answer

A

Explanation

As V = constant (because vessel is closed)
`rArrPpropT`
`rArr(DeltaP)/P=(DeltaT)/TrArr((DeltaP)/P)%xx100`
`rArr((DeltaP)/P)%=1/(250)xx100=0.4%`
