Can naphthalene sublime
WebDoes naphthalene sublime? Naphthalene is a solid that sublimes at standard atmospheric temperature with the sublimation point at around 80 C or 176 F. At low temperature, its vapour pressure is high enough, 1 mmHg at 53 C, to make the solid form of naphthalene evaporate into gas. 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 …
