A gas is heated through `2^(@)C` in a closed vessel. Its pressure is increased by 0.4%. The initial temperature of the gas is

A

`250^(@)C`

B

`100^(@)C`

C

`500^(@)C`

D

`227^(@)C`

Text Solution

Verified by Experts

The correct Answer is:
D
`(DeltaT)/(T)=(DeltaP)/(P)=(0.4)/(100)`
`(DeltaT)/(T)=(4)/(1000)=(1)/(250)`
`(2)/(T)=(1)/(250)`
`T=500K`
`4=500-273=227^(@)C`
