Pressure in Liquids

What is the formula to calculate pressure in a liquid column?

• P = ρgh

• P = gh

• P = ρh

• P = ρg

What is the SI unit of pressure?

How does the pressure in a liquid column change with an increase in depth?

• The pressure increases with depth.

• The pressure decreases with depth.

• The pressure is not affected by depth.

• The pressure remains constant with depth.

A liquid column of height 10 meters exerts a pressure of 1000 Pa at the bottom. What is the pressure exerted by the same liquid column at a depth of 5 meters?

• 750 Pa

• 500 Pa

• 250 Pa

• 1500 Pa

Which property of a liquid determines the pressure it exerts at a given depth?

What is the relationship between the pressure in a liquid column and the density of the liquid?

• Exponentially proportional.

• Directly proportional

• Unrelated.

• Inversely proportional.

A liquid column exerts a pressure of 5000 Pa at a depth of 8 meters. What will be the pressure exerted by the same liquid column at a depth of 12 meters?

• 9000 Pa

How does the pressure in a liquid column change with an increase in the area of the column?

• The pressure remains constant.

• The pressure becomes zero.

• The pressure increases.

• The pressure decreases.

A liquid column of height 2 meters exerts a pressure of 5000 Pa at the bottom. What will be the pressure exerted by the same liquid column if its height is doubled?
