A glass slab is subjected to a pressure of 10 atm. The fractional change in its volume is (Bulk modalus of glass `=37 xx 10^(9) Nm^(-2), 1 atm= 1 xx 10^(5) N m^(-2)`)A. `2.7 xx10^(-2)`B. `2.7 xx 10^(-3)`C. `2.7 xx 10^(-4)`D. `2.7 xx 10^(-5)`

Answer» Correct Answer - D
Bulk modulus, `B = (P)/(DeltaV//V)`
`therefore` Fractional change in volume, `(DeltaV)/(V)= (P)/(B)`
Here, `P = 10 "atm" = 10 xx 1 xx 10^(5) Nm^(2) , B = 37 xx 10^(9) N m^(-2)`
`therefore (DeltaV)/(V) = (1xx10^(6) N m^(-2))/( 37 xx 10^(9)N m^(-2))= 0.027 xx 10^(-3) = 2.7 xx 10^(-5)`
