Take a deep breath. In a single intake of air, your lungs swell with roughly 25 sextillion molecules, ranging from days-old compounds, to those formed billions of years in the past. In fact, many of the molecules you're breathing were likely exhaled by m
Clouds are floating water.There are plenty of water molecules floating eo in the air. When cold water molecules meet dust or salt, they stick together. It makes tiny water droplets.Clouds are made of these tiny water droplets.Where do clouds come from? As the sun warms the Earth, water ...
ECO ORIGIN™, certified low-carbon molecules Be it in terms of industrial performance or environmental footprint, Air Liquide always innovates to support its customers. Many industries use gases such as oxygen, nitrogen, argon and carbon dioxide (CO2) in their manufacturing processes, which can...
The atoms or molecules of matter in the gaseous state are in a constant state of motion. They move freely around each other and continuously collide with each other and the wall of the container that holds them. Usually, the atoms or molecules are packed more loosely than they are if the...
