SUMMARY
The discussion centers on the relationship between pressure and volume during an isothermal process, specifically using the ideal gas law, represented by the equation pV=nRT. Given an initial state with a gas at 30°C (303 K), a volume of 20 cm³, and a pressure of 2 x 10^5 Pa, the change in pressure when the volume decreases to 27 cm³ is calculated using the principle that p1V1 = p2V2. The final pressure can be determined without needing the temperature value, as the product of pressure and volume remains constant throughout the isothermal change.
