Questions Related to pressure in liquids
Pressure exented by the liquids on the walls of the container depends upon
-
density
-
declaration due to gravity
-
height of the liquids column
-
all
Pressure exerted by the fluids on the sides of the container is called lateral pressure. It depends on the all the given options, mathematically p = hpg
-
Air
-
Water
-
Kerosene
-
Both A and B are considered as most common fluids
-
Solids exert pressure on a surface due to their own weight.
-
Fluids also have weight.
-
Liquids can exert pressure.
-
All the above
A fluid is a substance that has no fixed shape, can flow easily and yields easily to external pressure, e.g., a gas or a liquid.
-
Air
-
The container in which they are stored
-
Both A and B
-
Their own molecules which are present on the surface of the container
How fluid pressure is different from solid pressure?
-
Solid pressure leads to deformity while fluid pressure doesnt
-
Solid pressure doesn't lead to deformity while fluid pressure leads to deformity
-
Both leads to deformity
-
Both doesn't lead to deformity
Solid pressure is different from fluid pressure in the sense that solid pressure leads to deformity while fluid pressure doesnt.
-
True
-
False
Since a fluid has no definite shape, its pressure applies in all directions. Fluid pressure can also be amplified through hydraulic mechanisms and changes with the velocity of the fluid.
The size of an air bubble rising up in water.
-
Decreases
-
Increases
-
Remains same
-
May increase or decrease
As the pressure exerted by water is directly proportional to the depth of water, as the depth of water increases in a water body, the pressure increases linearly. So when a air bubble rises in water, the pressure acting on the air bubble decreases.
In the rising air bubble, as the pressure is decreasing, the volume and hence its size increases.
so option (B) is correct.
Pressure inside an inflated balloon is
-
Less than atmospheric pressure
-
Greater than atmospheric pressure
-
Equal to atmospheric pressure
-
May be less than or equal to atmospheric pressure
The pressure in an enclosed fluid is transmitted _________ in all directions with diminished force
-
equally
-
unequally
-
cant say
-
none
Different liquids exert the _____ pressure at a given depth.
-
same
-
different
-
can't say
-
none
Different liquids will exert the different pressure at a given depth because of difference in their density.
