Is steam a pure substance?

Understand the Problem

The question is asking whether steam can be considered a pure substance. This involves understanding the properties of steam and whether it consists of only one type of particle (water molecules) or if it may contain impurities or other substances.

More Information

Steam, which is water in its gaseous state, is considered a pure substance because it consists of only one type of molecule: H2O.

Tips

A common mistake is to confuse a mixture of air and steam (which is not a pure substance) with pure steam (which is).
