A gas at `10^(@)C` occupies a volume of 283ml. If it is heated to `20^(@)C` keeping the pressure constant, the new volume will be

A

293 ml

B

283ml

C

566ml

D

586ml

Text Solution

Verified by Experts

The correct Answer is:
A
`V_(1) = 283 ml`,
`T_(1) = 273 + 10 = 283 K`
`V_(2) = ?`
`T_(2) = 273 + 20 = 293K`
At constant P,
`( V_(1))/( T_(1)) = ( V_(2))/( T_(2))`
or `V_(2) = ( V_(1)T_(2))/( T_(1))`
`V_(2) = ( 283 xx 293)/( 283) = 293ml`
