Rapid cooling is needed to form glass, specifically tempered glass, to make the glass stronger and safer.
Unlike regular glass which breaks when undergoing rapid cooling, tempered glass is ductile. It is not brittle and its ductility is a result of undergoing the rapid cooling process.
Through rapid cooling, tempered glass develops a core that has a large amount of tensile stress and a surface that has compressive stress. The compressive stress on the surface of the tempered glass makes it stronger than regular glass. It can also be broken but when it does, it breaks into small granular chunks that are less likely to cause injury.
Answer:
2.4E-4
Explanation:
Hello,
By applying the following mass-mole relationship, the concentration could be computed as follows (assuming molarity as long as it isn't specified), since in the silver carbonate two silver molecules are present:
Best regards.
Answer:
Ur answer is C. Their average kinetic energy
Explanation:
In chemistry, we define the temperature of a substance as the average kinetic energy of all the atoms or molecules of that substance. Not all of the particles of a substance have the same kinetic energy. ... It is the average kinetic energy of the particles that thermometers measure and we record as the temperature.
Explanation:
According to the works of Antoine Lavoisier , he stated that , mass is always conserved in a chemical reaction .
i.e. ,
When , carbon reacts with oxygen , it forms carbon dioxide ,
But , by using the principle of conservation of mass ,
mass can not created or be destroyed , hence , the mass of the initial state and final remains constant , there is only the transfer of mass or matter .
