What is Sublimation? [Class 9,10th,11th]

Sublimation is the process by which a solid or liquid substance is converted into a gaseous substance, without going through the liquid or solid state. It is a physical process of conversion that occurs when heat is applied to a substance. In this process, the substance is heated to its melting point and then rapidly cooled, causing a phase change to take place (the melting point is the point at which the solid and liquid phases merge into a single phase body).

Sublimation printers allow for a wide range of different media to be used, such as paper, fabric, metal, and plastic. This process differs from digital printing in that it uses heat and pressure to transfer the ink or dye from the printing plate to the substrate. The print is then fixed in place by heat and pressure from the sublimation process. This process can also be used for promotional items, such as t-shirts and sweatshirts.

What are examples of sublimation?

Example1: Dry Ice

When dry ice sublimes, it emits a high temperature gas called carbon dioxide gas that is far more dangerous.

Example2: Naphthalene balls

Naphthalene balls are a great alternative to conventional incense sticks. They’re also a great way to get rid of unwanted smells, such as cigar smoke. When you expose the naphthalene to heat, it releases a mixture of chemicals, including benzene, toluene, and xylene, which act as the active ingredients in typical incense sticks.

Example3: Frost formation

Frost formation is the process of clear ice crystals forming in cold, humid air. It has been observed in the process of freezing fog, frost formation caused by the condensation of water vapor in the atmosphere. The process is important in atmospheric chemistry and atmospheric physics.

Example4: Ammonium chloride

When ammonium chloride is heated, it decomposes into elemental chlorine gas and ammonium chloride.

Example5: Iodine

When iodine is heated, it forms a gas that has a strong, unpleasant smell. It is one of a few toxic gases that are flammable. Iodine is a colorless, odorless, and tasteless gas.

Q1: What is sublimation in Chemistry?

Ans: In chemistry, sublimation is a process in which a solid changes directly from solid to gas without the liquid phase.

Q2: What is sublimation in Geography?

Ans: In geography, sublimation is the process In geology, sublimation is the process by which ice is transformed directly into water vapour without going through an intermediate liquid phase.
