An ideal gas has a volume of 3.1 × 10−3 m3 at a pressure of 8.5 × 105 Pa and a temperature of 290 K, as shown in Fig. 2.1. volume 3.1 × 10−3 m3 volume 6.3 × 10−3 m3 pressure 8.5 × 105 Pa pressure 2.7 × 105 Pa temperature 290 K temperature TF Fig. 2.1 The gas suddenly expands to a volume of 6.3 × 10−3 m3. During the expansion, no thermal energy is transferred. The final pressure of the gas is 2.7 × 105 Pa at temperature TF, as shown in Fig. 2.1.
