1.	An `LPG` cylinder weighs `14.8 kg` when empty. When full it weighs `29.0 kg` and the weight of the full cylinder reduces to `23.2 kg`. Find out the volume of the gas in cubic metres used up at the normal usage conditions and the final pressure inside the cylinder. Assume `LPG` to be `n`-butane with normal boiling point of `0^(@)C`.
Answer» Weight of full cylinder `=29 kg` Weight after usage `=23.2 kg` Gas consumed `=29-23.2=5.8kg` or `5800 g` For butane `(C_(4)H_(10))`, `M=58` Normal pressure `=1 atm` Room temperature `=298 K` `PV=nRT` or `1xxV=(5800)/(58)xx0.0821xx298` or `V=2446.58 L~~2.447m^(3)`

The gases obey the different gas laws only theoretically. Practically all of them show some deviation from these laws. These are called real gases. The deviation are maximum under high pressyre and at low temperature. These are comparatively small when the conditions are reversed. It has been found that the easily liquefiable gases show more deviations from the ideal gas beheviour as compared to the gases which are liqufied with diffculty. Gas deviates from ideal gas beheviour because moleculesA. are coloulessB. attract each otherC. contain covalent bondD. show Brownian Movement.
