"Heated atmospheric air is frequently used in recreational ballooning. According to the Ideal gas law, an amount of gas (and also a mixture of gases such as air) expands as it is heated. As a result, a certain volume of gas has a lower density as the temperature is higher. The average temperature of air in a hot air balloon is about 212 °F (100 °C). Hydrogen, being the lightest existing gas (7% the density of air, 0.08988 g/L at STP), seems to b… " - Lighter than air materials
