Weather balloons are sent into space to gather data. The balloons usually burst at a
pressure of 27 640 Pa and a volume of 36,3 m3. The data collector then falls back to Earth.
The gas in a certain weather balloon has an initial volume of 12,6 m3 and pressure of
105 000 Pa at a temperature of 25 °C when it is released into space.
Calculate the:
5.1 Temperature of the gas, in °C, in the balloon when it bursts (4)
5.2 Initial amount of gas (in moles) in the balloon (4)
