At higher temperature, steam becomes the superheated steam. Steam is used as a source of energy, steam engine is the first step in this direction, now a day steam turbines are used for power generation and many other purposes. Gas is one of the three states of matter, when they are defined in classical way. When heat is provided to solid, it becomes liquid and then to gas. Sometime solid can turn directly to gas, without becoming liquid. Different elements have different boiling points.
Pure gases are made up of individual atoms, like Oxygen, Nitrogen and Helium, while others are mixture of two or more elements like carbon dioxide. When a substance comes in its gaseous phase, at temperature which is lower than its critical point, it is called as vapor.
Vapor can be condensed to liquid or solid by increasing the pressure only and keeping temperature, same. Vapor can co-exist with its liquid form, and in this condition both states are at equilibrium.
Smoke is the collection of airborne solid, liquid and gases, which are emitted as a result of combustion. Smoke is by product of fire, which is unwanted and considered as pollution these days. Smoke is also used as flavoring agent in some cases. Fumigation is a method for controlling pest growth. Here's a closer look at what steam and smoke are and the difference between them.
Steam is pure water vapor, produced by boiling water. Sometimes, water is boiled with other liquids, so there are other vapors with the water. Ordinarily, steam is completely colorless. As steam cools and condenses it becomes visible as water vapor and can produce a white cloud. This cloud is just like a natural cloud in the sky.
It is odorless and tasteless. Because the humidity is very high, the cloud may leave water droplets on solids that touch it. Smoke consists of gasses and soot.
The gasses typically include water vapor, but smoke differs from steam in that there are other gasses, such as carbon dioxide and sulfur oxides , plus there are small particles. The type of particles depends on the source of the smoke, but usually, you can smell or taste either the soot or some of the gasses from the smoke. Smoke may be white, but more commonly it is colored by its particles.
Color and odor are two ways to distinguish smoke and steam. Another way to tell smoke and steam apart is by how quickly they dissipate. Water vapor dissipates rapidly, particularly if the relative humidity is low. Smoke hangs in the air since the ash or other small particles are suspended. Actively scan device characteristics for identification. However, they have different properties that make it easier to tell these two from each other.
Steam is basically heated water vapor that is the gaseous phase of water. Steam forms when water is boiled to the point where it transitions from the liquid phase to the gaseous phase. Although, steam is considered to be invisible, it can be seen as a white mist escaping a boiling pot or kettle.
Steam is required to be hot and can transform back to water droplets when it cools down. At high temperatures steam is invisible, but it becomes visible as the temperature drops. This can be seen when water is boiling, as the steam rises above the pot it gets cooler and the steam can be seen as mist. Smoke is produced by burning matter such as wood, petrol, oil, rubber, etc.
Burning is a process that converts oxygen into carbon dioxide.
