Julie blows a bubble. At first, the pressure of the gas in the bubble is 4kPa. The bubble floats into the air and
expands. When it gets to the top of a tree the bubble has a pressure of 2kPa and a volume of 3.5m². Assuming a
constant temperature, what was the volume in m3 of the bubble when it was first blown?
