F5 Chapter 2.1 Liquid pressure

Diagram shows water spurting out from a container. The observation above shows that

• Liquid pressure decreases when the volume of liquid increases

• Liquid pressure decreases when the depth of liquid increases

• Liquid pressure increases when the volume of liquid increases

• Liquid pressure increases when the depth of the liquid increases

Diagram shows a diver dive into sea water and fresh water with different depth. Which diver will experience the highest pressure?

• A

• B

• C

• D

Observed the diagram, what is the relationship between y and p

• 
• 
• 
• 

• 107m

• 1070m

• 118.8m

• 1188m

Which column of liquid exerts the greatest pressure on the base of the container?

• 
• 
• 
• 

• 0.03Pa

• 30Pa

• 33.3Kpa

• 66.6Kpa

• 25.2Kpa

• 14.6Kpa

• 10.3Kpa

• 4.9Kpa

• 589Kpa

• 0.5Kpa

Diagram shows a dam and the thickness of the dam is larger at the bottom compare to the top. Why?

• So the dam will be more stable

• It is easier to make a larger base compare to larger top

• The water pressure increase when depth of water increase

• The inertia of the water is higher at the bottom of the dam compare to the top of the dam

How to reduce a pressure?

• Increase the gravitational acceleration

• Reduce the area of contact

• Reduce the gravitational acceleration

• Increase the area of contact
