The pressure of a gas contained in a clo...

The pressure of a gas contained in a closed vessel is increased by `0.4%` when when heated by `1^(@)C`. The initial temperature was

A

250 K

B

`250^(@)C`

C

25 K

D

`25^(@)C`

Text Solution

Verified by Experts

The correct Answer is:
a
`(P)/(T)="constant"`
`(DeltaP)/(P)-(DeltaT)/(T)=0`
`T=((P)/(DeltaP))DeltaT=(100)/(0.4)xx1, T=250K`
