Question

Agas occupies a volume of 5L at 27C.The temperature atwhich the volume would be 6.5L at a constant pressure is

Answer 1

Charles Law: V1/T1=V2/T2

5.0 L/300 K=6.5 L/T2

T2=390 K

390 K-273=117 degrees Celsius

Answer 2

using ideal gas equation, pv=nRT.

p = nrT / v

since p is a constant,

p1 = p2

therefore

nrT1 / v1 = nrT2 / v2

nR are constants, therefore equation further simplified to

T1/V1 = T2/V2

300 / 5 = T2 / 6.5

T2 = 390K
