Answer:
percentage change in volume = 0.00285 %
Explanation:
given data
bulk modulus = 3.5 × 
N/m²
bulk stress = 
N/m²
solution
we will apply here bulk modulus formula that is
bulk modulus = 
...............1
put here value and we get
3.5 × = 
solve it we get
bulk strain = 2.8571 × 
and
bulk strain = 
so that percentage change in volume is = 2.8571 × × 100
percentage change in volume = 0.00285 %
