The first balloons used were filled with hydrogen and sealed to keep the volume constant. As the balloon rose there would be changes in the pressure of the hydrogen due to the temperature changes of the atmosphere.
i. Calculate the new pressure exerted by the hydrogen if the temperature changed from 20.0 °C to −5.0 °C, as the balloon rose from ground level.
Pressure exerted by the hydrogen in the balloon at ground level = 1.01 × 105 Pa
ii. State two assumptions that you must make to calculate this change.?
