B. Statements given below are incorrect. Write
the correct statements.
1. Pressure exerted by a liquid is inversely
proportional to the density of liquid
2. The pressure in an enclosed liquid is
transmitted unequally in all directions with
diminished force.
3. Different liquids exert the same pressure at
a given depth
4. Deep sea divers wear specially designed
suits to protect themselves from deep sea
creatures.
Answers
Answer:
1. False statement.
The pressure exerted by a liquid depends on the height of the liquid column.
It can be defined as the weight of liquid column over an unit area.
So pressure is define as P=ρgH
2.False statement.
According to Pascal's law: Pressure in an enclosed fluid is transmitted equally in all direction with diminished force at all the points with same depth.
3. True statement
liquid exerts equal pressure at the same depth. ... The pressure exerted by a liquid changes with depth in the liquid. The pressure exerted by a liquid increases with increasing depth inside the liquid. The pressure exerted by a liquid is small just under the surface of the liquid.
4.True statement
The pressure exerted by water in the oceans increases with depth. Very deep down, the pressure is enough to crush the human body. That is why deep sea divers wear special suits which can withstand such high pressure and prevent their bodies to crush.
