Steam is the vapor that we see when water evaporates or turns from a liquid to a gas. When this happens, the molecules of water drift farther and farther apart from each other. That makes a gas. Steam, or water vapor, is only made up of tiny bits of water. The water boils and gets heated up to make Steam! Steam comes from boiling water or any other liquid that has water inside of it. Think of it like a hot day at the park. People will be spread out so that they are not too hot. When it suddenly gets colder, people bunch together at a specific spot to keep warm. That is basically how Steam is produced! Steam is just water in a specific state of matter, a gas.
