Adsorption is a surface phenomenon as it occurs at the interface between phases.

Coordination compounds can exhibit optical isomerism due to the arrangement of ligands around the central metal ion.

Galvanic cells convert chemical energy into electrical energy spontaneously.

A convex lens can form both real and virtual images depending on the position of the object relative to the focal point.

The law of conservation of energy states that energy cannot be created or destroyed, but it can be transformed from one form to another.

The nucleus of an atom contains protons and neutrons, which are collectively known as nucleons.

In an adiabatic process, there is no heat exchange with the surroundings, and the temperature of the system changes due to work done on or by the system.

In an isochoric process, the volume of the system remains constant.

The complex [Fe(CN)6]3- is a low-spin complex due to the strong field nature of CN- ligands, resulting in paired electrons.

A buffer solution is designed to resist changes in pH upon the addition of small amounts of acid or base.

Adsorption isotherms describe the relationship between the amount of adsorbate on the adsorbent and its pressure at a constant temperature, illustrating how adsorption varies with pressure.

Gravitational fields are always attractive, pulling masses towards each other.

Reduction is defined as the gain of electrons, and it always occurs simultaneously with oxidation in redox reactions.

The Freundlich adsorption isotherm is applicable to heterogeneous surfaces and describes how adsorption varies with pressure or concentration, indicating that it is not limited to monolayer adsorption.

The Freundlich adsorption isotherm describes heterogeneous adsorption on surfaces with varying affinities, making it suitable for real-world applications.

The uncertainty principle states that position and momentum cannot be precisely known at the same time.

Thermal conductivity is a measure of a material's ability to conduct heat; it varies with material and temperature.

Solids have a definite shape due to closely packed particles that do not move freely.

Liquids have a definite volume but take the shape of their container.

Plasma has the highest kinetic energy as it consists of ionized gases with free-moving charged particles.

Gases have the least intermolecular forces, allowing particles to move freely.

Phosphorus is essential for the formation of DNA as it is part of the backbone structure.

Carbon is known for its allotropes, including diamond and graphite.

PLA (Polylactic Acid) is a commonly used polymer in 3D printing due to its ease of use and biodegradability.

Teflon (PTFE) is known for its high heat resistance and non-stick properties.

The magnetic quantum number describes the orientation of an orbital.

Dehydration is a characteristic reaction of alcohols where they lose water to form alkenes.

Amines can be prepared from alkyl halides through nucleophilic substitution reactions where the amine acts as a nucleophile.

Amines can be prepared from alkyl halides through nucleophilic substitution reactions, where the halide is replaced by an amine group.

Nitriles can be converted to amines through reduction, typically using hydrogen in the presence of a catalyst.
