Many heat-sensitive and oxygen-sensitive solids, such as camphor, are purified by warming under vacuum. The solid vaporizes directly, and the vapor crystallizes on a cool surface. What phase changes are involved in this method?

Respuesta :

Since deposition is the opposite of sublimation, the answer is sublimation and deposition.

We'll examine the various changes that can take place in a vacuum. When purifying something, people occasionally use compounds that are heat- and oxygen-sensitive in a vacuum.

Therefore, if you take camper and heat it up in a vacuum, it will instantly change from a solid to a vapor. It's known as sublimation when a face changes. all at once. They have a metal plate that will take the vapor and cool it back into a solid since they are attempting to purify the chemical. Deposition refers to the opposite of sublimation.

What is sublimation?

Sublimation is the term used in science to describe a substance that transforms swiftly from a solid to a gaseous state. It does not undergo the conventional liquid stage and only occurs under specific pressure and temperature circumstances.

What does deposition mean in chemistry?

A gas can go from a liquid to a solid without first going through the liquid phase, which is known as the deposition phase transition. The thermodynamic process of deposition. Sublimation is the opposite of deposition, hence deposition is occasionally referred to as desublimation.
