Liquid Pressure Puzzles
Click on the buttons to reveal hints and answers!
1. Define liquid pressure.
Hint: It is related to the weight of the liquid.
Answer: Liquid pressure is the pressure exerted by a liquid due to its weight at a given point.
2. What is the SI unit of liquid pressure?
Hint: It is named after a scientist.
Answer: The SI unit of liquid pressure is Pascal (Pa).
3. What are the factors affecting liquid pressure?
Hint: Consider depth, density, and gravity.
Answer: Liquid pressure depends on depth, density of the liquid, and gravity.
4. How does liquid pressure change with depth?
Hint: Deeper levels experience more pressure.
Answer: Liquid pressure increases with depth.
5. How does the density of a liquid affect its pressure?
Hint: Denser liquids exert more force.
Answer: A denser liquid exerts more pressure for the same depth.
6. Why is the pressure at the bottom of a liquid greater than at the top?
Hint: Think about the weight of the liquid above.
Answer: The pressure is greater at the bottom because it supports the weight of the liquid above it.
7. Why do dams have a wider base than their top?
Hint: Greater pressure at the bottom requires more strength.
Answer: Dams have a wider base to withstand the greater pressure at greater depths.
8. Does liquid pressure depend on the shape of the container?
Hint: Focus on depth, not shape.
Answer: No, liquid pressure does not depend on the container's shape; it depends only on depth, density, and gravity.
9. Why do divers feel more pressure as they dive deeper?
Hint: Pressure increases with depth.
Answer: Divers feel more pressure as they go deeper because the water's weight above them increases with depth.
10. What is the relationship between liquid pressure and gravity?
Hint: Gravity pulls the liquid down.
Answer: Liquid pressure increases as gravity increases, as it affects the weight of the liquid.
