WebJan 6, 2024 · The solid piece of naphthalene when heated is observed to melt after it attains the temperature of 80° C and then this 80° C is called as it melting point. After 80° C naphthalene will start to melt and get transformed into liquid state. Also if this naphthalene is allowed to cool down after 80° C it will be the freezing point of naphthalene. WebCorrect option is C) Sodium Chloride is an ionic solid and has high melting and boiling points. So it can not change in vapour phase simply at atmospheric pressure hence it cannot sublime.
