What does density have to do with hot air balloons?
The burners on a hot air balloon create hot air, which rises into the balloon and displaces the cooler air from the balloon. Then the hot air, being less dense, will lift the balloon as the cooler...

The density of air is 1 kgm3 What is the density of air in gcm3?
Convert: 1kg/m3 to g/cm3 1kg=1000g 1m3=100*100*100=1000000cm3 therefore: 1000g/1000000cm3 = 0.001g/cm3 4200kg/m3 * 0.001g/cm3 = 4.2g/cm3

What does the burner do to the density of the air in a hot air balloon?
The intense heat of the burner alters the atomic nucleus of the oxygen atom into a synthetic helium atom causing the balloon to rise. The helium atom is less dense than the original oxygen atom.

What is air density?
Air density is the mass of air per unit volume, which changes by temperature, humidity, and elevation. Changes in air density will change its pressure. At mean sea level and 20°C, air has a density...

How does a hot air balloon change its density?
By use of the burners. The air is heated and it's density is reduced. Since Hot air is less dense, and therefore lighter than cold air, the balloon rises. It takes a lot of heat to do this, the...
