P5.25 Pressure in fluids (TRIPLE)

What is the relationship between pressure in a liquid and its depth?

• Pressure decreases with increasing depth.

• Pressure increases with increasing depth.

• Pressure remains constant regardless of depth.

Why does the pressure at the bottom of a liquid column depend on the weight of the column of liquid?

• Because weight is transferred to the sides of the container.

• Because weight is force per unit area.

• Because the liquid is incompressible.

What happens to the pressure in a liquid at the same depth?

• It varies depending on the container shape.

• It is always the same.

• It increases with the liquid's volume.

How does the density of a liquid affect the pressure at a given depth?

• Pressure decreases with higher density.

• Pressure increases with higher density.

• Pressure is unaffected by density.

What happens to the jet of water leaving holes at different depths in a bottle?

• The water jets out at the same force from all holes.

• The water from lower holes jets out further due to higher pressure.

• The water from upper holes jets out further due to less resistance.

What is the unit for pressure?

• Kilograms per cubic meter (kg/m³).

• Pascals (Pa).

• Meters (m).

What is the formula for calculating the pressure due to a column of liquid?

• Pressure = density × height.

• Pressure = height × gravitational field strength.

• Pressure = height × density × gravitational field strength.

Why is a diver's chest at greater depths under more pressure?

• Because the water is colder at greater depths.

• Because of the greater weight of the column of water above them.

• Because the water becomes denser at greater depths.

What is the symbol for density?

• ρ (rho).

• π (pi).

• δ (delta).

What is a "manometer" used for?

• Measuring the depth of a liquid.

• Comparing the density of different liquids.

• Measuring the temperature of liquids.
