Question

Where is the pressure greater, 10m or 20m below the surface of the sea? Give Reason.

Answer 1

20m
pressure in liquids is found using the formula p=h.density.acc due to gravity
and h =height!
pressure is directly proportional to height(in liquids)
therefore we can say that pressure is greater in 20m below sea level!

Answer 2

Pressure is greater at 20m.

For every 33 feet (10.06 meters) you go down, thepressure increases by 14.5 psi 

The deeper you go higher the pressure will be.

PRESSURE DECREASES WITH ALTITUDE AND INCREASES WITH DEPTH.
