Overview

Air density (ρ) is the mass of air per unit volume. It is affected by temperature, pressure, and humidity.

Fun Facts

"Humid air is actually less dense than dry air because water molecules are lighter than nitrogen and oxygen molecules."
"The density of air is why airplanes need longer runways at high altitudes or on very hot days."
"The lowest air density on Earth's surface occurs during major hurricanes due to very low pressure."

Formula: ρ = P / (R * T)
