A perfect gas or an ideal gas is a state of a substance, whose evaporation from the liquid state is completed and which obeys all the gas laws strictly under all conditions of pressure and temperature. In reality there is no ideal or perfect gas which obeys all the law of gas under all conditions of pressure and temperature. But the real gases such as oxygen, hydrogen, nitrogen and air which are ordinary difficult to liquefy; within certain range of pressure and temperature may be considered as perfect gas or ideal gas. The behavior of a perfect gas can be studied with the following gas laws that are proved from experimental results. It states that under constant temperature, the absolute pressure of a given mass of a perfect gas varies inversely as its volume. Suppose we have a cylinder piston assembly which contains a gas.

Gas Laws – Boyle’s, Charles, Gay Lussac, Avogadro and Ideal Gas Law
When the volume is held constant, the pressure exerted by a gas is directly proportional to the absolute temperature of the gas. In simple terms, increasing the temperature of a gas increases its pressure, while decreasing temperature decreases pressure, assuming volume does not change. The law is also known as Gay-Lussac's law of pressure temperature. Gay-Lussac formulated the law between and while building an air thermometer.
Crushing a can by heating it, sealing it and cooling it rapidly is an excellent demonstration of the existance of atmospheric pressure. Many youtube videos describe the crushed can as an illustration of either Charles' Law or Gay-Lussac's Law. I don't agree. There are many variations on the theme, but the basic experiment involves heating a small amount of water inside of a metal container usualy a soda can. The can is then sealed and cooled rapidly.
