Sublimation is the process by which a substance directly changes from a solid directly into a gas, without passing through the liquid phase. It involves the transfer of energy and the breaking of bonds between molecules, resulting in the formation of a gas at a higher temperature.
Examples:
Dry ice (solid CO2) sublimates directly into carbon dioxide gas when exposed to heat.
Certain materials, such as hydrogen and iodine, sublime directly at room temperature.
When a piece of ice is placed in hot water, the ice sublimates into water vapor
