At constant pressure the volume of a gas is Vat `0^(@)C.` At which temperature it will be 3V?

A

`300^(@)C`

B

`273 ^(@)C`

C

`573^(@)C`

D

`546^(@)C`

Text Solution

Verified by Experts

The correct Answer is:
D
`V _(1) = V`
`V _(2) = 3 V`
`T _(1) = 0^(@) C= 273 K`
`T _(2) = ` ?
According to Charle.s law
`(V _(1) )/( T _(1)) = (V _(2))/( T _(2))`
` ( V)/( 273) = ( 3 V)/( T _(2))`
`VT _(2) = 3 V xx 273`
`T _(2) = ( 3 V xx 273)/(V) = 819 K - 273 = 546 ^(@) C`
