PHYSICS [1 Mark Question Answer]

The body of the deep sea fish burst when brought up to the surface of the sea water because the body of fish contains dissolved oxygen at much higher pressure than the atmospheric pressure.

The hull of Submarines are specially Strengthened so that they can prevent it from collapsing from the high pressure of the water outside while it is submerged. Roughly every 30 feet of depth under water adds another atmosphere of inward pressure on the hull

The pressure exerted by liquids increases with depth. So, as the depth increases, more pressure is applied to the walls. That is why walls are made thicker at the bottom, so that they can handle the pressure exerted by water.

Pascal’s law says that pressure applied to an enclosed fluid will be transmitted without a change in magnitude to every point of the fluid and to the walls of the container. Therefore pressure at any point in the fluid is equal in all directions.

Pressure due to a liquid is inversely proportional of the area of cross-section of containing vessel.

the pressure due to a liquid at a point inside the liquid increases with the acceleration due to gravity at that point.

Liquid pressure increases with the increase in density of the liquid.

Deep sea divers wear specially designed suits to protect themselves from deep sea pressure.

Different liquids exerts the different pressure at a given depth.

The pressure in an enclosed liquid is transmitted equally in all directions with diminished force.

Pressure exerted by a liquid is directly proportional to the density of liquid.
