Sublimation is a phase transition of a substance from the solid state directly to the gas state without passing through the liquid state. This process occurs when the pressure of a substance is reduced and the temperature is increased. In this article, we will discuss which of the following substances is not capable of sublimation.
What Is Sublimation?
Sublimation is the process by which a solid substance is transformed directly into a gas without passing through the liquid state. This process occurs when a solid is heated and the pressure is reduced. As the temperature increases, the solid particles begin to vibrate faster and faster, until they eventually break free from the lattice of the solid and enter the gas phase.
Sublimation is a reversible process, meaning that the gas can be transformed back into a solid when the temperature and pressure are adjusted. This process is commonly seen in the formation of ice crystals, snowflakes, and frost, as well as in the evaporation of water and other liquids.
Substance Not Capable Of Sublimation
Not all substances are capable of sublimating. The following are some of the substances that cannot undergo sublimation:
- Metals: Metals are generally too dense and heavy to be able to sublimate.
- Carbon: Carbon is not capable of sublimation as it has a strong bond between its atoms.
- Salts: Salts are made up of multiple different elements and compounds, which prevents them from being able to sublimate.
- Plastics: Plastics are too heavy and rigid to be able to sublimate.
In conclusion, while many substances are capable of undergoing sublimation, there are some substances that cannot undergo this process. These substances include metals, carbon, salts, and plastics. Understanding which substances are capable of sublimation can be useful for various applications, such as in the production of snowflakes and frost.
