Question

Deep sea divers put on special suit to
(A) Maintain their body temperature in cold sea water
(B) Protect against sea animals
(C) Maintain pressure
(D) Keep them dry

Answer 1

Hint As we go down to the deep of the sea the depth increases, the pressure increases since pressure increases with depth so the scuba divers go to depth of the sea. Our human body has some limit of resistance

Complete Step by step solution
As we know that humans can resist only to some specific range of pressures.
As the scuba divers go to the depth of the sea gradually the pressure increases since pressure increases with depth. The pressure exerted by water deep under the sea is much greater than at the sea level
Divers select which suits to wear based on the conditions like temperature, environment, in which they will dive.
 Diving suit allows very deep dives of up to 2,000 feet .These suits are capable of resisting the pressure at great depth allowing the diver to remain at normal atmospheric pressure. This eliminates the problems associated with breathing high-pressure gases.
 They are made from thick Neoprene, which provides good thermal protection, but lose buoyancy and thermal protection as the trapped gas bubbles in the neoprene foam compress at depth.

Hence option C is correct.

Additional Information
 So do you ever wonder why suits are black?
Sharks are believed to see contrast particularly well, so any high contrast colour apparel or gear used by a human in the water is especially visible to sharks.

Note
Let’s first understand and learn the reasons for each and every option. So what happens to the person when the person goes to the depth of the sea and gets related to the following options.
