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?
Sodium chloride become a liquid at 801 0C.
What is the residue when sodium chloride water solution was heated to dryness?
When a mixture of sodium chloride and water is heated to dryness, the residue is sodium chloride, because the boiling point of sodium chloride is much higher than the boiling point of water.
What residue is left after sodium chloride is heated?
After 1 413 0C pure sodium chloride is vaporized without any residue.
What colour flame test do sodium sulphate and potassium chloride give?

What colour changes will appear when phenolphthalein is mixed with sodium chloride solution?
Sodium Chloride is neutral. And Phenolphthalein is colourless when neutral.
Is sodium chloride a liquid gas solid or aqueous?
Sodium Chloride is not a gas solid. It is in crystalline form which when heated, becomes molten. It never evaporates to give Sodium Chloride gas i.e. NaCl.
