Question:

A 15.0-cm-long cylinder has a movable piston with radius 2.00 cm.

(a) What is the volume of the cylinder?

(b) If the initial air pressure is 101 kPa at 0.0°C, what is the air pressure inside the cylinder when the piston is pushed down 4.00 cm?

(c) If the air temperature inside the compressed cylinder is heated to 20.0°C, what is the new air pressure?

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.
