Compare and contrast melting and sublimation. Can all materials sublime?

Sublimation describes a solid turning directly into a gas. Melting occurs when a solid turns into a liquid. Water can, under the right circumstances, sublimate, though it usually melts at temperatures above 0 degrees Celsius or 32 degrees Fahrenheit.

Explanation: Carbon dioxide (CO2), however, is very different. The conditions that determine whether CO2 melts or sublimates are both temperature and atmospheric pressure.

Sublimation is the process in which a solid molecule converted directly into gas while melting is a process in which a solid molecule converted first into liquid. and No all the materials cannot be sublime.
