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

A

`0.4%`

B

`0.2%`

C

`0.1%`

D

`0.8%`

Text Solution

Verified by Experts

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