When you heat something it becomes lighter, if it started of as a solid it will eventually become light enough to be a liquid, and liquids become gases. When you heat water to 100 degrees Celsius (212 degrees Fahrenheit) it becomes light enough to become vapour, at this point it also becomes lighter than air so it immediately rises. The reason you can see steam is that when it floats it cools from the air and forms droplets.
When water is heated rapidly and changes into steam, this process is called boiling.
a phase change from liquid to gas that occurs when water is heated to its boiling point. This process requires energy to break intermolecular bonds and cause the water molecules to transition from a liquid state to a gaseous state.
Chemical changes are those in which the chemical composition of a substance changes during the process. But when steam turns into water or vice versa, only the physical state of the substance undergoes a change but the chemical composition remains same. Thus steam turning into water is a physical change.
The steam when cooled changes back to liquid water
The process when water changes into a gas is called evaporation. Evaporation occurs for pure water at 100 degrees celsius (-173 K) when water molecules begin to move around very rapidly and split up.
When water is heated rapidly and changes into steam, this process is called boiling.
Evaporation
The process that changes water into a gaseous state is called evaporation, where water is heated and transforms into vapor or steam.
No, steam is the gaseous form of water resulting from boiling or heating liquid water. Evaporation is the process in which liquid water changes into water vapor at the surface of the water.
it is a physical change because you can actually see the process
Yes, steam can be changed back into water through a process called condensation. When steam loses heat energy, it changes into water droplets. This can be achieved, for example, by allowing steam to cool inside a container.
You can turn steam back into water by condensing it, condensation is a process which changes a gas into water.
Water changes to steam and can evaporate.

It is by condensation that water vapor changes to liquid water.
