7. Activity (2L Hindenburg)
- When the pressure and temperature of an ideal gas are constant, the volume of the gas is directly proportional to the amount of gas in moles. Prove this relationship using the Ideal Gas Law equation.
- Hypothesize the fraction of your bottle’s volume that must be filled with hydrogen and the fraction that must be filled with oxygen to achieve the optimal mixture. Justify your logic clearly. (hint: the combustion of hydrogen gas produces water).
- Label your bottle precisely. You will be filling your bottle upside down, and will add the oxygen gas first.
- Fill your 2L bottle with oxygen gas then hydrogen gas as demonstrated in class.
- Cap tightly and prepare for launch.
