Answer» Solution :(i) Boyle : Robert Boyle in 1662 did trustable measurement of gaseous properties. Boyle.s Low : At constant temperature, volume of fixed amountof any gas is inversely proportional to its pressure... `p prop (1)/(V )""` (at constant T and n) `therefore p=k_(1)(1)/(V)` (II) JACKS Charle.s Law : Jacks Charle.s performed several experiments on gases independently to improve upon hot air BALLOON technology. Their inverstigations showed that for a fixed mass of gas at constnat pressure, volume of gas increases on increasing temperature and decreases on cooling. `V prop T` (at constnat n and p) (ii) Joseph Gay LUSSAC : Pressure in well inflated types of automobilesis almost constant, but on a hot summer day this increases considerably and tyre may burst if pressure is not asdjucted properly. During winters, on a cold morning one may find the pressure in the types of vehicle decreased considerably. Law : ..At constant volume, pressure of a fixed amount of a gas varies directly with the temperature. `p prop T` (at constant n and V) `therefore (p)/(T)=k_(3)=` constant (iv) Avogadro Law : In 1811 Italian Scientist Amedeo Avigardro tried to combined conclusions of Dalton.s atomic theory and Gay Lussac.s law of COMBINING volumes which is now known as Avogadro Law. Law : It states that equal volumes of all gases under the same conditions of temperature and pressure contain equal number of molecules. `V prop n` (at constant T and p) where, n is the number of moles of the gas. `therefore V=k_(4)n` |
