Question 3
F

A gas has a volume of 2.0 m3 and a pressure of 100 000 Pa100\,000\ \text{Pa}100000 Pa.

The gas is compressed to a volume of 1.0 m3. 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 pressure of the gas?
