Question

which correctly lists three characteristics that are used to describe air?
altitude, density, radiation
density, radiation, mass
mass, pressure, density
pressure, altitude, radiation

Explanation:

• Altitude: It is the height of a location above sea level and is not a characteristic of air itself but rather a location - related measure.
• Radiation: It is energy in the form of waves or particles and is not a fundamental characteristic of air.
• Mass: Air is made up of gases (such as nitrogen, oxygen, etc.), and like any matter, it has mass.
• Pressure: Air exerts pressure (atmospheric pressure) due to the weight of the air column above a given point.
• Density: Density of air ($

ho=\frac{m}{V}$, where $m$ is mass and $V$ is volume) is a characteristic property as it can vary with temperature, pressure, and composition.

Answer:

mass, pressure, density
