Use the ideal gas equation:
PV = nRT
=> PV/T = nR
The amount of substance 'n' and the universal gas constant 'R' is the same in this case, hence, PV/T will remain constant:
=> (PV/T)1 = (PV/T)2
(Note that temperature must be taken in Kelvin)
=> (760*200)/(300) = (760*V2)/(270)
=> V2 = 270*(2/3)
= 180
Since the answer is obtained in the same units as V1, the volume is 180 cm cube
Volume of a gas at 27degree centigrade and 760mm pressure is 200cm cube then find the volume of same gas at -3degree centigrade and 760mm pressure
