At what temperature in the celsius scale, V ( volume ) of a certain mass of gas at 27^(@)C will be doubled keeping the pressure constant ?

Answer»

`54^(@)C`
`327^(@)C`
`427^(@)C`
`527^(@)`

Solution :`(V_(1))/( T_(1)) = ( V_(2))/(T_(2))` at constant PRESSURE
`(V)/( 300) = ( 2V)/( T_(2))`
or `T_(2) = 300 xx2 = 600`
or `= 600 - 273 = 327^(@) C`
