A famous example would be carbon dioxide (CO2). Changing from a solid to a gas is called sublimation and happens for most substances at certain temperatures and pressures. The substances that are known for subliming are the ones that do it at atmospheric pressure and room temperature.
Solids that can change directly from the solid to gaseous state , without passing on to the liquid state are called sublimable solids. Examples are Iodine, Carbon Dioxide (dry ice), Naphthalene (moth balls) and Ammonium Chloride.
The process in which a substance turns directly from a solid to a gas is called sublimation. Iodine and solid carbon dioxide (dry ice) are some substances that sublime.
iodine and it is used in finding fingerprints by the police.
It turns from a solid to a gas at a low temperature.
Sublimation
i am a solid substance left after heating coal or petol
Melting: the substance changes back from the solid to the liquid. Condensation: the substance changes from a gas to a liquid. Vaporization: the substance changes from a liquid to a gas. Sublimation: the substance changes directly from a solid to a gas without going through the liquid phase.
The process in which solid directly changes into gas is called sublimation. Solid carbon dioxide is a substance that changes directly into gas without melting. Sublimation happens because these substances have higher vapor pressure than melting point.
When a substance is heated, a heating curve shows the changes in temperature as well as the physical state of the substance. A heating curve can chart the temperature versus the time elapsed as the changes take place.

Sublimation.
solidification
A phase change directly from a gas to a solid is called deposition.
A phase change directly from a gas to a solid is called deposition.
A phase change directly from a gas to a solid is called deposition.
A substance which changes state directly from a solid to a gas is said to have sublimed.
Because the entropy is negative making it spontaneous.

When a substance changes from liquid to solid is called freezing.
A substance changes from a solid to a liquid at its melting point
