What is Noncondensable? Definition and Examples

Noncondensable refers to a substance that does not condense or change state when it comes into contact with another substance. In other words, it does not undergo a phase transition or become liquid when it interacts with another substance.

In the context of steam and water, water vapor is a noncondensable substance because it does not condense or turn into liquid water when it comes into contact with cold surfaces or water droplets. Instead, it continues to exist as a gas and can be seen as steam.

On the other hand, condensable substances are those that do undergo a phase transition and become liquid when they come into contact with another substance. For example, water is a condensable substance because it will turn into liquid water when it comes into contact with a cold surface or water droplets.
