Ch3: Pressure Exerted by Liquids

The pressure exerted by a liquid

• increases with depth.

• decreases with depth.

• is constant

• first increases and then decreases.

Pressure exerted by liquids at the bottom depends on

• width of the liquid column.

• shape of the column.

• shape of the container.

• height of the liquid column.

What is up thrust?

• It is another term for gravitational force.

• The force that liquid pushes floating objects up with.

• A type of energy.

• It is the same as weight of an object.

The unit of up thrust in S.I. system is ___________

• Newton

• gf

• m/s

• Dyne

Four different liquids are poured into identical measuring cylinders. The diagrams show the depths of the liquids and their densities.

Which liquid causes the largest pressure on the base of its measuring cylinder?

• A

• D

• C

• B

The pressure of the water at the bottom of a pond is ___ at the surface of the pond.

• either lower or higher

• higher than

• same

• lower than

Which of the following does not affect the pressure beneath the surface of a liquid?

• Strength of the gravitational field

• Area of the liquid surface

• Density of the liquid

• Depth of the liquid

The diagrams show, to the same scale, the vertical sections of a set of circular vessels, each containing the same depth of water.

• The water exerts the same pressure on the base of each vessel.

• The water exerts the greatest pressure on the base of vessel S.

• The water exerts the greatest pressure on the base of vessel P.

• The water exerts the same force on the base of each vessel.

Pressure exerted at any point of an enclosed liquid is transmitted

• towards the sides of vessel.

• towards the base of vessel.

• in all directions.

• upwards only.

What type of liquids are measured using a manometer?

• Heavy liquids

• Medium liquids

• Light liquids

• Heavy and light liquids
