Water or H2O is a substance that sprouts naturally, it is vital to create and maintain life; be it animal, vegetable and even human. Likewise, water has certain peculiarities that identify it, and one of them is that it is composed of fused oxygen and hydrogen molecules.
Water is a substance that is not only found on earth, but can also be found in the solar system. Thus, water can be found in three ways, in its liquid, solid or gaseous state , of course in space it is in the form of vapor or ice.
What is the melting of water?
The melting point is the passage of a component that is in a solid state to a liquid. Although, the water also suffers or undergoes a fusion process that consists of the previously explained.
A clear example of this would be ice cubes: When a group of ice cubes are taken from the low temperature to which they were subjected and are exposed to room temperature, or failing that, high temperatures; these (ice cubes) one way or another are going to start to melt.
When the whole fusion process is complete, all the cubes will no longer be solid but will become totally liquid. Temperature plays a role in this process, if the melting is likely to occur quickly at very high, on the contrary, if they are low, the cubes will take a significant time to become fully liquid .
Characteristics of Water Fusion
- Water changes after a temperature that is constant.
- The melting point of water is considered a physical property of matter.
- The melting of water, unlike other processes such as boiling, is not affected by pressure.
- The melting point of water is executed to carry out other chemical processes, where water participates as a key indicator of purity. The higher its purity level, the higher the melting point.
Examples of fusion of water and other elements
- Melt ice: either by placing it on a higher temperature or by exposing it to heat. Icebergs are a clear example of this process, since they go through it naturally when moving from one station to another.
- Melting candles: when the wick of a candle is lit and it is consumed to the point of heating the surface of, worth the redundancy, the candle, it will begin to melt. The candles melt with the heat, but the difference it has with the melting of water is that they are solid again when they lose contact with the heat.
- Metal casting : Shaping a metal is an arduous process since, being resistant and extremely solid materials, heat is needed to be able to mold them.
There are large companies that work with metals, they use this process to be able to fuse them with other metals or in the same way give them the shape they want.
States or Phases of Water
- Solid phase: It is when the water has a compact structure, mainly crystalline. The solid particles are no longer so separated, on the contrary, they are quite united and ordered, they cause that result.
- Liquid phase: liquid water adapts to the container that contains it. Liquid water has a lot of mobility since the particles that make it up no longer have an order as with the previous phase.
- Gaseous phase: in the gaseous phase, water is in the form of vapor. The boiling causes the particles are quite far apart, making it difficult to take completely liquid or solid form.
Types of water
- Drinking water : it is suitable for human consumption, for preparing food, medicine, etc.
- Fresh water: Fresh water is similar to drinking water, the difference is that it has not undergone a “cleaning” process, this is what we see in lakes, rivers, streams, etc.
- Salt water: water that comes mainly from the sea. This water is characterized by having high levels of saltpeter in them. This water cannot be consumed by the majority of living beings that do not live within it.
- Distilled water : This type of water goes through a distillation process, it has been purified.
- Wastewater : This type of water has no value. What’s more, it is considered dirty water, as it contains high levels of garbage and pollution.
- Black water : It is that water that is contaminated with urine and feces.
