What Does Sublimation Mean?

Sublimation is known as the conversion of a substance from its solid state directly to be gaseous phase, during the process of sublimation there is no intermediate phase of liquid. The effect of sublimation is a type of a phase transition that only takes place at pressures and temperatures below the triple point.

Sublimation at normal pressures in various chemical compounds or different types of elements possesses three very different states at different temperatures. In many cases the transition of an element from its solid state to its gaseous phase, the element needs to pass through the intermediate liquid state however there are various elements that can achieve the gaseous state without going through the liquid phase. These elements are known as sublime elements. Zinc and cadmium is sublimate at low pressures.

When a solid goes directly to gas state without entering the liquid state or vice versa

There are three states of matter that exist on Earth – solids, liquids and gases. A substance can exist in all three forms, but does so at different temperatures. A solid changes to a liquid at the melting point of a substance and a liquid changes to a gas at the boiling point of a substance.

When a solid that is heated changes straight from a solid to a gas, without becoming a liquid in between, this is described as sublimation. Iodine is one element that exhibits sublimation. At room temperature iodine is a dark grey solid but at 30 degrees Celsius, it sublimes into a purple vapour.

Actually sublimation means when a state changes into another without any other states being produced
