The volume of a gas measured at 27^(@)C and 1 atm pressure is 10L. What final temperature would be required to reduce the volume to 5.0 L at 1 atm pressure ?

Answer»

450K
327K
150K
`100^(@)C`

SOLUTION :`V_(1) = ` 10L, `T_(1)` = 273 `+ 27 = 300K`,
`p_(1) = `1 ATM
`V _(2) =`5L,
`T_(2) = ?`
`p_(2) =` 1 atm
Since pressure is constant ,
`( V_(1))/( T_(1)) = ( V_(2))/( T_(2))`
or `T_(2) = ( V_(2))/( V_(1))xxT_(1) = ( 5)/( 10) XX 300`
