A mass of gas under constant pressure occupies a volume of 0.5 m3 at a temperature of 20°C. Using the formula for cubic expansion, 0.5457875 m³ will be the volume at a temperature of 45°C without a change in pressure.

Solution: T1 / V1 = T2 / V2; V2 = T2 x V1 / T1; V2 = 318.15 x 0.5 / 293.15; V2 = 0.5457875 m³.
