The volume of a given mass of a gas at 27°C, 1 atm is 100 cc. What will be its volume at 327°C?

Here there is two cases,


Case 1


T1=27° C=27+273=300 K


V1=100 cc


Case 2


T2=327° +273=600 k


V2=?


By Ideal Gas equation,


where P, V and T are the pressure, volume and absolute temperature; n is the number of moles of gas; R is the ideal gas constant. Considering the two cases,


, as P, n and R are constant, where V1, T1 and V2, T2 are volume and absolute temperature of first and second case respectively.


Substituting the values,
