As sodium chloride is heated, the vibrations of the individual sodium chloride molecules increase, forcing adjacent sodium chloride molecules to move away until they have enough room to vibrate. Once the temperature increases to 801 °C (1,474 °F), the molecules are so far apart that they can't hold together anymore. So, they fall apart and act as a liquid. Viola, molten sodium chloride.

What does sodium chloride become when heated?
When heated, sodium chloride (table salt) remains as solid salt. When heated to very high temperatures, around 801°C (1474°F), it will melt into a liquid form. Only when it reaches the extreme temperature of 1465°C (2669°F) does it decompose into its constituent elements, sodium and chlorine.
Is dissolving sodium chloride a chemical or physical change?
Dissolving sodium chloride in water is a physical change because the chemical composition of sodium chloride remains the same. The sodium and chloride ions are simply dispersed throughout the water, but they can still be recovered by evaporating the water.
Will sodium chloride change Methyl orange yellow?
no
Which will not form water and carbon dioxide when it burns?
Sodium chloride (table salt) will not form water and carbon dioxide when it burns. When sodium chloride is heated, it may decompose into sodium and chlorine, but it does not produce water and carbon dioxide as products.
Is sublimation of sodium chloride chemical or physical change?
Sublimation is a physical change.
