State the relationship between depth and pressure in a liquid. A2. Pressure increases as depth increases (because there is more weight of liquid above).
Explain why your ears ‘pop’ during takeoff in an aeroplane. A7. Outside air pressure decreases rapidly at high altitude; pressure inside the ear is initially higher, so air pushes out until equalised. aqa science p2 5.5 activity sheet answers
What is upthrust? A8. An upward force exerted by a fluid on an object immersed in it (caused by higher pressure at the bottom of the object than at the top). State the relationship between depth and pressure in
