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.

What happens when substances goes through a phase change?
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.
Examples of changing a solid into a gas?
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.
A heating curve shows?
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.
What happens to a substance during changing between a solid to a liquid?
When a substance changes from a solid to a liquid and vice versa, its density changes.
What is the phase in which a substance changes from a gas directly to a solid?
A phase change directly from a gas to a solid is called deposition.
