- melting point is a specific characteristic of a substance; consequently we can distinguish these substances knowing the melting point
- the knowledge of the melting point is absolutely necessary to design technological processes, to made alloy, to use surely materials at high temperature, etc.

What elements are rare have high densities an used in industrial purposes?
Some rare elements with high densities that are used in industrial purposes include tungsten, osmium, and iridium. These elements are prized for their hardness, resistance to corrosion, and high melting points, making them valuable in various industrial applications such as in manufacturing tools, electrical contacts, and catalysts.
How are melting and freezing points similar in a chemical?
Melting and freezing points are both physical properties of a substance related to its phase change from solid to liquid (melting) or liquid to solid (freezing) at a specific temperature. These points are the same temperature for a pure substance under constant pressure and can be used to identify and characterize substances.
Melting point of eudragit L100 and S100?
The melting point of Eudragit L100 is around 160-170°C, while the melting point of Eudragit S100 is higher, around 200-220°C. Both polymers are commonly used in pharmaceutical formulations for coating purposes.
Why is cookware not made of ionic compounds?
Ionic compounds are not suitable for cookware because they are not good conductors of heat. Metals such as aluminum and stainless steel are commonly used in cookware because they conduct heat efficiently and evenly. Additionally, ionic compounds have high melting points, which would make them impractical for cooking purposes.
What is the melting point of glass used as a substrate?
The melting point of the glass used as a substrate can vary depending on the specific type of glass. However, most common types of glass substrates have melting points ranging from about 600°C to 1000°C. It is important to consider the specific properties of the glass when using it as a substrate for various applications.
For what two reasons are the melting points routinely used?
Melting points are routinely used to determine the purity of a substance. Impurities often lower the melting point of a substance, so a lower-than-expected melting point can indicate the presence of impurities. Melting points are also used to identify unknown substances by comparing their melting points to established values.
What elements are rare have high densities an used in industrial purposes?

These elements are prized for their hardness, resistance to corrosion, and high melting points, making them valuable in various industrial applications such as in manufacturing tools, electrical contacts, and catalysts.
What similar properties do lead and gold have?
Lead and gold are both heavy metals that are dense and malleable. They are relatively unreactive and have high melting points, making them useful in various industrial applications. Additionally, both lead and gold have been used historically for jewelry and decorative purposes due to their lustrous appearance.
Is it safe to attempt melting glass at home for crafting purposes?
No, it is not safe to attempt melting glass at home for crafting purposes as it requires high temperatures and specialized equipment that can be dangerous if not used properly. It is recommended to leave glass melting to professionals or use pre-made glass products for crafting projects.
How are melting and freezing points similar in a chemical?
Melting and freezing points are both physical properties of a substance related to its phase change from solid to liquid (melting) or liquid to solid (freezing) at a specific temperature. These points are the same temperature for a pure substance under constant pressure and can be used to identify and characterize substances.
What are the meterials used in fse wires?
Low temperature melting point materials like copper, aluminium, tin or lead are used to make the fuse wire. Zinc and antimony are also used because of their low melting points.
How can laser be used in surgery?
They are used routinely for eye surgery.
Alloys are used in electrical heating devices rather than pure metals. Give reason.?
Alloys are used rather than pure metals in electrical heating devices since they have low electrical conductivity and also a low melting point. Usually the alloys don't have a single melting point; they have a range of melting points. The temperature at which melting begins is called the SOLIDUS and the temperature at which melting is complete is called the LIQUIDUS.Student

Can Filtration can be used to separate mixtures based on their boiling point?
It is not possible; filtration as a separating method is based on the difference between boiling points.
