Turning materials
In order to change the form of water in nature, living organisms can benefit from it. When it is steamy, it softens the temperature of the weather and dampens it. And makes it suitable for life, and this steam may turn into water in the process of condensation to become liquid in the water bodies, and was able to exploit these characteristics of some other materials, such as minerals, which can be mixed after melting to be homogeneous together, what is the degree of fusion? What factors affect them?
Definition of fusion
Fusion is the transformation of matter from hardness to liquidity. Solid matter is supplied with heat. The solid part begins to melt and melt as a result of the breakdown of the bonds between its molecules. In the solid material, the fusion begins at the degree that the solid and liquid components of the material are in equilibrium. And the temperature at which the melting point is "melting point" and measured by a unit of joule per kilogram. When the material is kept in heat, it remains stationary until it breaks down the bonds between its molecules and turns into the gaseous state in the form of vapor.
Factors affecting the degree of fusion
There are several factors that influence the degree of material fusion:
Atmospheric pressure: The higher the atmospheric pressure, the greater the melting point and the greater the heat required to complete the fusion process.
The purity of the material: When the material consists of one element, the fusion process is done in a homogeneous while if it consists of a set of elements and each element a degree of fusion that makes the process is not homogeneous, and scientists were able to rely on this information to know the purity of the material if it melted at the temperature It is pure, but if it melts at different degrees, it is composed of a mixture of materials.
Freezing
The freezing process is an opposite process of fusion. It occurs when the liquid is cooled and placed at a low temperature. Its particles converge and the gravitational force of each other becomes more solid. This transformation takes place at a certain temperature for each substance. At zero temperature, the temperature at which the material begins to freeze is called "freezing." The degree of freezing of the material is affected by its purity. The more it is pure, the more it freezes at a certain temperature, while the mixture is frozen at different temperatures.
