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, the volume at a temperature of 45°C without a change in pressure is 0.5457875 m3. V1/T1 =V2/T2 , 20C= 293.15K , 45 C= 318.15 , 0.5/ 293.15 =V2/318.15 , V2 =0.5 * 318.15 / 293.15 = 0.545.
