Sodium Chloride (Salt) has a lattice structure and since it is a solid, there is limited movement of the atoms within the structure. The structure of water is very different, the molecules of water are linked through hydrogen bonds and inter-molecular bonds within the individual water molecules . The molecules in water can also move more freely relative to those in salt.
This means that more energy is required to break the bonds within the lattice structure of salt since there are a greater number of bonds connecting the atoms. The bonds between water molecules are broken with less energy, hence water boils at a lower temperature than salt decomposes (it does not 'melt').
It's due to the nature of the compunds. Water is a covalent molecule, which generally have low melting points due to weak intermolecular forces, whereas salt is an ionic lattice, which usually have high melting points because energy is needed to overcome the electromagnetic force binding the ions together.
By adding calcium chloride to sodium chloride, the melting point of the mixture is reduced because calcium chloride is a salt that disrupts the sodium chloride lattice structure. This disruption makes it easier for the sodium chloride to transition from a solid to a liquid state, lowering its melting point.
Sodium hydride decomposes at temperatures above 400°C, releasing hydrogen gas in the process.
Copper would be in liquid form at 800 degrees Celsius. Copper has a melting point of 1084 degrees Celsius, so at 800 degrees, it would have already melted but not yet boiled into a gas.
Calcium chloride and calcium fluoride are added to the electrolyte in the down cell during the extraction of sodium metal to improve the conductivity of the electrolyte. This helps in the smooth flow of electric current during the electrolysis process, ensuring efficient extraction of sodium metal. Additionally, these compounds help to increase the melting point of the electrolyte, which is important for maintaining the high temperatures required for the extraction process.
At 800 degrees Celsius, gold will be in a liquid state. Gold has a melting point of 1064 degrees Celsius, so at 800 degrees Celsius it would have melted from its solid state into a liquid.
The melting point of sodium chloride (NaCl) is 801 degrees Celsius or 1474 degrees Fahrenheit.

No. The salt does not melt in water, but it dissolves in water. The melting point of common salt (sodium chloride along with other metal salts as impurities) requires very high temperatures (exceeding 800 Degrees C) to melt. The process of melting and dissolving in a solvent are two distinct and totally different ball games, if you will.
A solid with a high melting point of 800 degrees Celsius is more likely to be ionic rather than molecular. Ionic compounds typically have higher melting points compared to molecular compounds because of the strong electrostatic forces between the charged ions in the crystal lattice.
Table salt does not change into a liquid at 808 degrees. Table salt, which is sodium chloride, has a melting point of 1474 degrees Fahrenheit (801 degrees Celsius). This means that it needs to be heated to a higher temperature to turn into a liquid.
Cerium (58) has a melting point of 799 deg C.

Bohrium's melting point is not well-defined due to its synthetic nature and short half-life. Its estimated melting point is around 600-800 degrees Celsius.
A glass hasn't a true melting point. The softening point of Pyrex glass is between 800 °C and 850 °C.
The water will boil if its temperature is brought high enough. The significant difference between boiling water and boiling water with sodium chloride in it is that the NaCl water will boil sooner. Adding salt to water will lower its boiling point as well as its freezing point. This is also why the road is salted in sub zero weather: to hinder the road from becoming icy.
The seashell is fomed from calcium carbonate; CaCO3 is thermally decomposed by heating.
