A gas occupies a volume of 300 cc at 27∘C and 620 mm pressure. Find the volume of the gas at 47∘C and 640 mm.
310 cc
Given,
Intial temperature T1 = 27∘C
Final temperature T2 = 47∘C
Intial pressure P1 = 620 mm
Final pressure P2 = 640 mm
Intial volume V1 = 300 cc
Using Ideal gas equation,
P1V1T1 = p2V2T2
620×300300 = 640×V2320
V2 = 310 cc
