Take a tin can with a lid. Fill it approximately with half of water. Heat the can on a candle flame till the water boils. Let the water boil for a few minutes. Blow out the candle. Immediately put the lid tightly on the can. Be careful in handling the hot can. Put the can carefully in a shallow metallic vessel or a washbasin. Pour fresh water over the can.
THE CAN GETS DISTORTED DUE TO THE AIR PRESSURE EXERTED.
If you can't get a tin can, take a soft plastic bottle. Fill it with hot water. Empty the bottle and immediately cap it tightly. Place the bottle under running water.

What are five examples of convection?
Here are 2 examples: - hot airballoon - hot air rising, and cold air falling.
Examples of objects that are buoyant?
Some examples are, hot air ballons, ships, bouys, actually just about anything that floats in air or water :p
Why is the term a cubic meter of air unsatisfactory?
Because it doesn't say neither the temperature, the pressure or the humidity of the air. You need to know both the temperature, the pressure and the humidity of the air to say anything about the mass of one cubic meter of air.
Why is a ping pong ball pulled toward running water?
Running water moves the air next to it. Moving air has less pressure than air that is still. This is the Bernoulli principle, and helps airplanes to fly. With less pressure on one side from moving air, and more pressure on the other side from still air, the ping-pong ball moves towards the water.
Real life situation involving function examples?
Functions are an integral part of mathematics, and most students learn them from Algebra II and up. A real life example of a function would be the relation between the height of a ball and how long it has been in the air.
