The pressure of a gas filled in a closed...

The pressure of a gas filled in a closed vessel increase by 0.4% when temperature is increased by `1^(@) C`. Find the initial temperature of the gas.

A

`23^(@)C`

B

`250^(@)C`

C

`-23^(@)C`

D

`300K`

Text Solution

Verified by Experts

The correct Answer is:
C
`(DeltaT)/(T)=(DeltaP)/(P)`
`=(0.4)/(100)=(4)/(1000)`
`(1)/(T)=(1)/(250)`
`T=250K`
`t=250-273=-23^(@)C`.
