Is it a Gas or Vapor?

Many people hear the terms gas and vapor interchangeably. In their basic sense, the gas and vapor is the exact same thing. The only difference is that vapor is a word that can describe the gas that will become a liquid when at room temperature. There are a couple of examples of what liquids become a gas, mercury and water. These two compounds are a liquid when they are at room temperature, but when heated up, they become a gas. It’s likely that you have heard the term water vapor, which is the gas state of water. On the other hand, compounds like carbon dioxide, will be a gas when at room temperature. It is rare to ever hear a scientist talk about vapor when discussing carbon dioxide. This post is brought to you by our sponsors Locksmith Management.

There is a lot of energy stored in gases. Their molecules are widespread, filling the container where they are stored. It takes little effort to compress a gaseous system, especially compared to liquids or solids. Engineers and scientists use the easy compression of gas for many different things. In fact, they will often use decreased temperature and increase in pressure combinations force gas into the many containers that are used every day.

There’s a good chance that you have felt carbon dioxide as it rushes out of the sun I can, or felt the compressed air as it is sprayed out of the bottle. Both of these examples are situations where gas is forced into a space that is smaller and at a greater pressure. When you introduce the gas to an environment that has a lower pressure, it will quickly rush out of container. The molecules of gas will quickly move from a high pressure area to one that has a lower pressure.

So, now that you know what a gas and vapor are, you can impress your friends with your knowledge.
