If pressure of a gas contained in a closed vessel is increased by `0.4%` when heated by `1^(@)C`, the initial temperature must be

A

250 K

B

`250^@C`

C

2500 K

D

`25^@C`

Text Solution

Verified by Experts

The correct Answer is:
A
Closed vessel i.e., volume is constant
`thereforeP_1/P_2=T_1/t_2rArr P/(P+((0.4)/(100))P)=T/(T+1)rArrT=250K`
