Question:
The diving bell below contains trapped air at the same pressure as the water outside. At the surface, air pressure is 100 kPa. As the bell descends, the pressure on it increases by 100 kPa for every 10 m of depth.
a. What is the pressure on the diver at depths of 0 m, 10m, 20m and 30m?
b. At the surface, the bell holds 6 m3 of air. If the bell is lowered to a depth of 20 m, and no more air is pumped into it, what will be the volume of the trapped air? (Assume no change in temperature.)

For this experiment we need-One glass bottle (opening slightly smaller than an egg)-A matchbox-One peeled boiled eggIn this demonstration, the lit matchsticks heat the air inside the bottle. When air is heated it expands and some of it escapes out of the bottle. When the matches go out, the air inside the bottle cools and contracts thus creating a lower air pressure area inside the bottle than outside. Normally, the high-pressure air outside the bottle would come rushing in to equalize the low-pressure air in the bottle. The problem is that the egg is in the way. The air molecules on the outside of the bottle push the egg into the bottle.•Procedure• Place a glass bottle on the table.• Boil a normal-sized egg and• Place the boiled egg on the face or neck of the bottle.• We can see the egg cannot be pushed into the bottle because of air inside the bottle.• Now light the matches at the same time and drop them into the bottle.• Once the matchsticks have been dropped into the bottle Quickly Place the egg over the neck of the bottle.• You can see the egg is sucked into the bottle.This represents the air pressure and characteristics of air.
