altitude
Odensity
O mass
O pressure
radiation​

Answer 1

Density and Pressure

Step-by-step explanation:

Density and Pressure are characteristics used to describe air.

Answer 2

The characteristics that are used to describe air are:

• Density
• Mass
• Pressure.

Step-by-step explanation:

• The density of air differs from one place to another so density characterizes the characteristics of air on that place.

• Similarly, pressure and mass also determines the characteristics of air. In normal temperature and pressure the air has the pressure of 1atm and density of
  `\bold{1.204 (k g)/(m^(3))}`
• In this way air is characterized by the density, pressure and mass.
