Steam and also water vapor space both used to explain water in the gas state.
You are watching: Is water vapor the same as steam
Sometimes, we use these terms interchangeably because they are describing the same concept. There is a subtle difference, though, i m sorry we can understand by thinking around different develops of water in the gas state. As soon as you cook water, you view water in the gas state coming turn off of the fluid water tho in the kettle. We know from suffer that this gaseous water is hot. The term for this form of water is steam. on the various other hand, us can also see gaseous water in the form of clouds or fog. The term for this type of water is usually water vapor.
The difference between vapor and water vapor is the distinction in temperature that the water molecules. You would certainly not it is in wrong to contact the gas water coming off a cook kettle "water vapor," yet saying "steam" lets us understand that this gaseous water is in a vapor state and also is hot. Water in the gaseous state can constantly be referred to as "water vapor," and we deserve to think that "steam" together a form of water vapor--hot water vapor.
This is a standard "rectangles-squares" question. All vapor is water vapor, but not every water vapor is steam. Water vapor just method the gas type of water. Water is a molecule, not particularly a liquid. The is a liquid at room temperature, and we require it in liquid type to live, therefore we regularly use the word "water" to average "liquid water," however really water deserve to be a heavy (ice), fluid (what we contact plain water), or gas (water vapor). Steam is the certain case where the water is a gas because it is at or over its boiling point (100 C). an instance of water vapor the is not steam would it is in humidity- this is simply water that diffuses into the air as result of something referred to as vapor-liquid equilibrium, i beg your pardon is basically the propensity for any type of liquid to provide off part gas molecules, also if it is no boiling.
when a kettle boils- that produces vapor because the boiling procedure is what causes the water to revolve to gas. The droplets you room describing, however, space liquid water. As the steam cools down, it as soon as again turns earlier into a liquid.
Steam and also water vapor, scientifically speaking, both describe water molecule in the gas phase, in other words, the water molecules that easily float in the air. However, we typically use the word "steam" to describe the visible condensation the water molecules in the air, while us most often use the hatchet "water vapor" to describe the invisible water molecules over a body of fluid water. because of these conventions, we regularly use the word heavy steam to define the white cloud over a boil kettle.
Steam and also water vapor space the very same thing.
Technically, the white cloud of water droplets is precisely that: a cloud, and the procedure that creates it is specifically the very same as the procedure that creates clouds in the sky. World often contact it "steam" due to the fact that they form when vapor comes into call with cooler air and also condenses to kind droplets, yet technically, it"s a misuse of words "steam".
Water vapor is water together a gas, wherein individual water molecules are in the air, separate from every other. Steam is what you see above a cook kettle.

steam is warm water in droplets almost big enough to view - yet you can see the cloud of droplets.
There must be stages in between, where a couple of water molecules room sticking to each other, yet the droplet is too small to see. If it"s a hot day and also the family member humidity is close to 100%, I"m guessing there will be water molecules the stick to every other, at the very least briefly.
