Helium Hero needs to get to the top of Ideal Gas Mountain to collect all of the balloons before the local wildlife eats them. Helium Hero sets out in a hot air balloon containing 250.0 L of atmospheric gases at 20.0°C and 760. mmHg. Helium Hero heats the atmospheric gases to a temperature of 99.0°C to rise to an altitude equal to that of the mountain's peak.
Helium Hero's starting point is a park in Seattle, Washington. The balloon catches the trade winds and drifts to the top Ideal Gas Mountain. As it drifts, Helium Hero studies the gas laws. Helium Hero ponders the following:
- According to Boyle's Law, if the pressure increases, what happens to the volume?
- According to Charles's Law, if the temperature decreases, what happens to the volume?
- According to Gay-Lussac's Law, if the temperature increases, what happens to the pressure?
- According to Avogadro's Law, if the number of moles decreases, what happens to the volume?
After this careful study and balloon collection, Helium Hero continues to fly to Sacramento, California to land the hot air balloon.
Once there, Helium Hero applies their knowledge of gas laws to a combustion reaction, content in having saved the day.
