1.	A refrigeration tank holding `5.00 L` feron gas `(C_(2)Cl_(2)F_(4))` at `25^(@)C` and `3.00 atm` pressure developed a leak. When the leak was discovered and repaired, the tank has lost `76.0 g` of the gas. What was the pressure of the gas remaining in the tank at `25^(@)C`?
Answer» Original gas pressure `n=(PV)/(RT)=(3.00atmxx5.00mL)/(0.082xx348)` `=0.613 mol=0.613xx171 g` `=105 g` originally present Quantity remaining `105-76=29 g=(29)/(171)=0.17 mol` `P=(nRT)/(V)=(0.17xx0.082xx298)/(5.00 L)=0.83 atm`

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.
