📄 Worksheet: Fluid Pressure Practice Problems

1. What is the formula for pressure in fluids?

-- Select your answer -- Force × Area Force / Area Area / Force

Incorrect. Pressure = Force divided by Area.

Correct!

2. Which unit is commonly used for pressure?

-- Select your answer -- pascal (Pa) newton (N) joule (J)

Incorrect. Pressure is measured in pascals (Pa).

Correct!

3. Pressure increases with:

-- Select your answer -- Depth Height Temperature

Incorrect. Pressure increases as depth increases in a fluid.

Correct!

4. Pressure in a fluid at a given depth depends on:

-- Select your answer -- Area only Volume only Density and depth

Incorrect. It depends on the density of the fluid and the depth.

Correct!

5. Which instrument measures fluid pressure?

-- Select your answer -- Manometer Thermometer Barometer

Incorrect. A manometer measures fluid pressure.

Correct!

6. What pressure is exerted by a fluid of density 1000 kg/m³ at a depth of 2m (g = 10 m/s²)?

-- Select your answer -- 500 Pa 20000 Pa 1000 Pa

Incorrect. Use Pressure = density × g × depth = 1000 × 10 × 2 = 20000 Pa.

Correct!

7. Fluid pressure is independent of:

-- Select your answer -- Shape of container Depth Density

Incorrect. Fluid pressure does not depend on the container’s shape.

Correct!

8. Atmospheric pressure at sea level is approximately:

-- Select your answer -- 500 Pa 101325 Pa 100 Pa

Incorrect. Standard atmospheric pressure is about 101325 Pa.

Correct!

9. Which fluid has the highest pressure at the same depth?

-- Select your answer -- Oil Alcohol Mercury

Incorrect. Mercury is denser and exerts higher pressure at same depth.

Correct!

10. Pascal’s Law applies to:

-- Select your answer -- Fluids at rest Fluids in motion Solids only

Incorrect. Pascal’s Law applies to fluids at rest.

Correct!
