Derive ideal gas equation. |
|
Answer» SOLUTION :The gaseous state is described completely using the FOLLOWING four variables T, P, V and n. Each gas law relates one variable of a gaseous sample to another while the other two variables are held constant. Therefore, combining all equations into a single equation will enable to account for the CHANGE in any or all of the variables. Boyle.s law : `V PROP 1/P` Charles.s `V prop T` Avogadro .s law `V prop n` We can combine these equations into the following general equation that describes the physical behaviour of all gases. `V prop (nT)/(P)` `V=(nRT)/(P)`, where R = Proportonately constant. The above equation can be rearranged to give PV = nRT - Ideal gas equation. Where, R is ALSO known as Universal gas constant. |
