Micro-Tutorial #3 – Characteristics of Air

Air Occupies Volume

The chemical makeup of air as a mixture of gases is one way to describe air (Micro-Tutorial #2 – What is Air?). We can also describe air with other characteristics, such as volume, weight, density, temperature, pressure, and movement (i.e., wind speed and direction). Understanding all the ways we describe air (the atmosphere) and the relationships between all of these characteristics is necessary for predicting the future state of the atmosphere (weather forecasting). Meteorologists use all of these characteristics to predict hurricanes, snow storms, tornados, and more.

Air occupies space and has mass. Here is a quick video demonstration of how air occupies space!
