1.6. Key questions in studying pressure

Try these first

1. 1.

   What happens to pressure as you go deeper underwater?

   Hint

   Think about how weight is distributed in layers.

2. 2.

   Explain Pascal's Law in your own words.

   Hint

   Consider how a balloon behaves when you squeeze it.

3. 3.

   True or False: Pressure increases with depth in a liquid.

   • True
   • False

   Hint

   Consider a diver going deeper underwater.

4. 4.

   What is Pascal's Law?

   Hint

   Think about the behavior of fluids in a balloon.

5. 5.

   A submarine can dive to a depth of 300 meters. Calculate the pressure exerted on it at that depth. Assume the density of water is 1000 kg/m³.

   Hint

   Use the same formula for pressure we discussed earlier.

6. 6.

   Discuss how design considerations would vary for a dam located at sea level versus one at a higher elevation.

   Hint

   Consider how altitude impacts pressure.
