1000 gm water is heated from `27^(@)` C to `47^(@) C` at a constant pressure of 1 bar . The coefficient of volume
expansion of water is `0.002//^(@)`C and the molar volume of water at `0^(@)` is `18.00cm^(3)//"mol"`. The magnitude
of work done (in J) by water is

Explanation

`V_(t^(@)C)= V_(0^(@)C) (1 +gammat)" "gamma="coefficient of volue expansion "`
`V_(27^(@)C)= 1000 (1 +0.002 xx27)" "t =" temperature in ".^(@)C `
`= 1054 ml`
`V_(47^(@)C) =1000 (1 + 0.002 xx 47)`
`=1094 ml`
`W =-PDeltaV =(-1 xx(1094 - 1054))/(1000)"bar litre" =(-4)/(100) "bar litre"=(-4)/(100) xx100J = - 4 J`
