A gas has a pressure of 150 000 Pa150\,000\ \text{Pa}150000 Pa and a volume of 0.020 m3.
The pressure of the gas is changed to 60 000 Pa60\,000\ \text{Pa}60000 Pa. The temperature of the gas stays the same.
Use the equation: pressure×volume=constant\text{pressure} \times \text{volume} = \text{constant}pressure×volume=constant
What is the new volume of the gas in cm3\text{cm}^3cm3?
