Question

By howmuch the pressure on one litre of water be changed to compress it `0.2%` ? Given the bulk modulus of water `-2.2 xx 10^(9)Pa`.

Answer 1

Here, increase in pressure, `p=?`
`(DeltaV)/(V) = (0.2)/(100) = 0.002 , B=2.2 xx 10^(9)Pa`
As `B=(p)/(Delta V//V)`
so `p=B xx (Delta V)/(V) =(2.2 xx 10^(9)) xx 0.002`
`=4.4 xx 10^(6) Pa`.
