Question

The compressiblity of water per unit atomsphere pressure is 4×109

Answer 1

436pa is the answer.

Answer 2

1 atm pressure =105N/m2

C=B1=4×10510−5m2/N

=4×10−10m2/N

P=100atm,V=100cm3

41010=100×10−6ΔV−100×105

41010=ΔV−103

ΔV=−4×10−7m3

=−0.4cm3

-ve sign indicates that volume is decreased.
