In order to increase the volume of a gas to `3` times at constant pressure at `40^(@)C`, the final temperature should be

A

`666^(@)C`

B

`777^(@)C`

C

`555^(@)C`

D

`333^(@)C`

Text Solution

Verified by Experts

The correct Answer is:
A
`(T')/(T) = (3V)/(V) = 3`
`T' = 3T = 3[40+273]K`
`=3xx313K = 939K`
`T = (939-273)^(@)C = 666^(@)C`.
