Pressure In A Fluid (GCSE Physics)

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 syringe contains trapped air. When you push the plunger slowly reducing volume, the pressure increases because:

A weather balloon rises, the surrounding atmospheric pressure decreases. The balloon expands because:

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

A fluid exerts pressure because its particles collide with surfaces; which direction is this pressure exerted?

Which equation gives hydrostatic pressure at depth h:

A stone of volume 0.002 m3 is fully submerged in water (? = 1000 kg/m3). The buoyant force (upthrust) on the stone is approximately:

A garage measures tyre pressure with a gauge showing 220 kPa. This is the gauge (above atmospheric) reading. The absolute pressure in the tyre (atmospheric ~101 kPa) is:

A manometer shows a higher column of liquid on the side open to air than the side connected to a closed container. This indicates:

A boat floats because the upthrust equals the weight of the boat. Upthrust depends mainly on:

Why does pressure act in all directions at a point in a static fluid?
