Pressure In A Fluid (GCSE Physics)

A cubic block 0.20 m side floats with half its volume submerged. The block’s density is:

For a given depth in the same liquid, hydrostatic pressure is doubled if:

A diver goes from 2 m to 6 m depth in seawater (? = 1025 kg/m3, g = 9.8 N/kg). The increase in pressure (approx) is:

A hollow cube of side 0.10 m is filled with water. If the pressure at the bottom due to the water is 980 Pa, what force does the water exert on the bottom?

An object sinks in a liquid if:

A sealed container of liquid is heated. The pressure inside increases because:

Which statement describes Pascal’s principle?

A pump increases fluid pressure in a pipe. If the flow area at a downstream section decreases, what happens to the local fluid speed and pressure (assuming incompressible steady flow)?

A cylindrical dam wall of area 12 m2 experiences a water force of 1.5 × 10^5 N. The water pressure at that depth is:

A fire piston compresses air rapidly and its temperature rises. Which effect increases inside the piston?

A rectangular plate 0.50 m by 0.20 m supports a force of 600 N from a fluid. What is the pressure on the plate?
