Chemistry Sublimation

Sublimation

Sublimation is the process in which a solid directly changes into a gas without passing through the liquid phase. This process occurs when the temperature and pressure of the solid are raised to a point where the molecules have enough energy to break free from the intermolecular forces holding them in place and escape into the gas phase.

Sublimation Point

The sublimation point is the temperature and pressure at which the solid and gas phases of a substance are in equilibrium. At this point, the vapor pressure of the solid is equal to the pressure of the gas. The sublimation point is typically higher than the melting point of a substance.

Chemistry Tetravalency Of Carbon

Tetravalency of Carbon

Carbon is a chemical element with the symbol C and atomic number 6. It is a nonmetallic element that belongs to Group 14 on the periodic table. Carbon is one of the most abundant elements in the universe and is the basis of all known life.

Why is Carbon Tetravalent?

Carbon has four valence electrons, which means that it can form four covalent bonds with other atoms. This is known as carbon’s tetravalency. The tetravalency of carbon is due to the electronic configuration of the carbon atom.

Chemistry Thermal Equilibrium

Thermal Equilibrium

Thermal equilibrium is a state in which the temperature of two or more objects or systems is equal. When objects are in thermal equilibrium, there is no net flow of heat between them. This means that the objects are at the same temperature and are not exchanging heat with each other.

Achieving Thermal Equilibrium

Objects can reach thermal equilibrium through conduction, convection, or radiation.

Chemistry Unit Cell

What is a Unit Cell?

A unit cell is the smallest repeating unit of a crystal lattice. It is a three-dimensional parallelepiped that contains all the information necessary to describe the entire crystal. The unit cell is defined by the vectors that connect the lattice points, which are the points where the atoms or molecules of the crystal are located.

Types of Lattices

There are many different types of lattices, each with its own unique properties. Some of the most common types of lattices include:
