HOW IS PRESSURE OF A LIQUID RELATED TO DEPTH? HOW WOULD YOU DEMONSTRATE THIS?
Relation between pressure and liquid :-
Pressure at a depth h in a liquid = g x depth (h) x density of liquid (r);
where g is the acceleration due to gravity.

DEMONSTRATION

The pressure in a liquids increases with depth
Get a can or a large plastic bottle with a series of holes drilled in the side one above the other. Cover the holes with your fingers or a piece of sticky tape and then fill the container with water.
Now remove the tape. The water gushes out but comes out faster from the holes nearer the bottom where the water is deeper and so the pressure of the water is greater.
Just imagine doing the experiment with a high-density liquid. The pressure would be much greater.
