Gas and gas laws

Describe the gas and gas laws? The Gas and gas laws Described here: Gas and gas laws Ideal gas 1) Ideal gas is the gas which strictly obeys gas laws, like Boyle's law, Charles's law etc. 2) For ideal gas, the size of the gas molecules is zero and the volume of the gas molecule is also zero. 3) There is no face of attraction or repulsion amongst the molecules of an ideal gas. 4) Molecules of an ideal gas have only kinetic energy. 5) The ideal gas cannot be liquefied or solidify, which supports the absence of inter molecular forces of ideal gas. 6) Internal energy of an ideal gas in independent of volume. 7) The internal energy of an ideal gas depends upon the  temperature . 8) No gas available in the universe is strictly an ideal gas. 9) The gas such as Hydrogen, Oxygen, Nitrogen and mono-atomic insert gases behave very similar to ideal gases. 10) Real gases at low temperature behave as ideal gases. 11) Real gases obey gas equation i.e. PV = nRT.
