Because they have densities lower than that of air, some gases are buoyant in air and are used to fill lighter-than-air crafts like balloons, airships, and other aerostats. Heated air is also an effective lifting gas because the density of a gas decreases as its temperature increases as long as pressure remains constant. What are some gases that are lighter than air?
