which correctly lists three characteristics that are used to describe air?\naltitude, density, radiation\ndensity, radiation, mass\nmass, pressure, density\npressure, altitude, radiation
Answer
Brief Explanations:
Air can be described by its mass (amount of matter), pressure (force exerted per unit area), and density (mass per unit volume). Altitude is a location - related measure and radiation is not a fundamental characteristic to describe air itself.
