Question

The law that explains that of deep sea fishes when suddenly brought to surface is
(P) Charles law
(Q) Grahams law

Answer 1

Dear student

In deep seas, there is more pressure than on the surface and they survive there, by creating the same pressure inside their bodies. So, if we try to bring fishes from deep suddenly to the surface their body would not be able to adapt to this sudden change in pressure.
And acc. to Charles law,
Pressure(P) is inversely proportional to Volume (V)

This quick lowering in pressure will increase the volume occupied by the fluids and muscles will increase rapidly and the fish will die exploding.

Hence, Charles law explains why deep-sea fishes shouldn't be suddenly brought to the surface.
