When a gas filled in a closed vessel is ...

When a gas filled in a closed vessel is heated through `1^(@)C ` , its pressure is increased by 0.4 % . The initial temperature of the gas was

A

`250K`

B

`350K`

C

`450K`

D

`500K`

Text Solution

Verified by Experts

The correct Answer is:
A
`PV=RT` here `V=` Constant therefore `P alpha T`. i.e. `=(P)/(T)` constant
`(P_(1))/(T_(1))=(P_(2))/(T_(2))implies(P)/(T)=(P+0.4%"of" P)/(T+1)impliesT=250K`
