fluoridation
The chemical name for the process of hardening vegetable oils is hydrogenation. This process involves the addition of hydrogen atoms to unsaturated fatty acids in the oil to make them more saturated and solid at room temperature.
Excess water (over hydration) causes weak concrete. The water in concrete is there to start a chemical process which results in the hardening process. The excess water is not used in the chemical process and results in a weakened concrete.
Cement hardening is not an example of melting. Melting involves a substance changing from a solid to a liquid state due to heat, while cement hardening is a chemical process where the cement mixture reacts and forms bonds to create a rigid solid structure.
Wood filler hardens through a process called curing, which involves the evaporation of solvents and the chemical reaction of the filler components. Factors that can affect the hardening process include temperature, humidity, thickness of the filler layer, and the type of filler used.
UV light initiates a chemical reaction in the resin that causes it to harden. The UV light activates molecules in the resin called photoinitiators, which then start a chain reaction that leads to the hardening of the resin.
No hydrogenating is the absorption of water, hardening is the process of something getting harder.
Most cases of osteoporosis occur as an acceleration of this normal aging process, which is referred to as primary osteoporosis
Case hardening, also referred to as surface hardening is the process of hardening a surface of a metal. It is done by surfacing the metal surface with a layer of metal on top of it, in order to harden it.
"calcification"
Case hardening or surface hardening is the process of hardening the surface of a metal, often a low carbon steel, by infusing elements into the material's surface, forming a thin layer of a harder alloy.
The type of energy that causes cement to dry is chemical energy. When water is added to cement, a chemical reaction called hydration occurs, where the water molecules react with the cement particles to form new compounds. This reaction releases energy in the form of heat, which helps to drive the hardening and drying process of the cement. The hydration process is essential for the formation of strong and durable concrete structures.
