The nitrogen pressure swing adsorption system of fire protection systems generates nitrogen at high pressures. Using the relative solubilities of nitrogen and oxygen gases at standard temperature and pressure (1 atm, 25 °C), explain why a nitrogen generator, particularly a nitrogen pressure swing adsorption system is necessary to continuously displace oxygen in fire protection systems.
Explain how high pressure allows for the successful production of sparkling water. Note that the solubility of carbon dioxide in water is 0.169 g/100 mL at standard temperature and pressure (1 atm, 25 °C).
When the temperature decreases, a gas in a liquid is _____ soluble and a solid in a liquid is ____ soluble.
