The key difference between essential and non-essential amino acids is that essential amino acids cannot be synthesized by the body, whereas non-essential amino acids can be synthesized by the body. Amino acids are the building blocks or precursors of proteins. As its name implies, amino acid contains an amino group (-NH2) and an acidic carboxyl […]
Difference Between Atomic Absorption and Atomic Emission
The key difference between atomic absorption and atomic emission is that atomic absorption describes how atoms absorb certain wavelengths from the electromagnetic radiation whereas atomic emission describes how atoms emit certain wavelengths. Absorption and emission of an atom help to identify atoms and provide many details about them. When absorption and emission spectra of a […]
Difference Between Gay-Lussac Law and Pascal Principle
The key difference between Gay-Lussac law and Pascal principle is that Gay-Lussac law is basically concerned with the properties of gases while Pascal principle is concerned with the properties of fluids. Gay-Lussac law and Pascal principal are two important concepts we discuss in physics. Gay-Lussac law is very important to describe the properties of gases. Pascal […]
Difference Between Photon and Quantum
The key difference between photon and quantum is that photon is an elementary particle, whereas quantum is a measure of quantity. Photon is an elementary particle while quantum is a discrete packet with energy stored in it. Photon and quantum are two very important concepts in modern physics. Furthermore, these concepts are useful widely in […]
Difference Between Nucleophile and Electrophile
The key difference between nucleophile and electrophile is that the nucleophile is a substance that seeks a positive centre whereas the electrophiles seek negative centres that have extra electrons. We can name the species arising due to a charge separation as “electrophiles” and “nucleophiles”. We will discuss what is exactly a nucleophile or an electrophile […]
Difference Between Deuterium and Tritium
The key difference between deuterium and tritium is that deuterium nucleus has one neutron whereas tritium nucleus has two neutrons. Hydrogen is the first and smallest element in the periodic table, which we denote as H. It has one electron and one proton. We can categorize it under group 1 and period 1 in the […]
Difference Between Compressible and Incompressible Fluids
The key difference between compressible and incompressible fluids is that the compressible fluids occur in reality whereas the incompressible fluids is a concept developed for ease of calculations. Fluids are either gases or liquids that take the shape of the container. In fluid dynamics, the compressibility of a fluid is a very important factor. In […]
Difference Between Titration and Back Titration
The key difference between titration and back titration is that in a titration, we usually add a chemically equal amount of standard solution to the analyte whereas, in a back titration, we add an excess amount of standard solution to the analyte. Titrations are techniques we mainly use in analytical chemistry to determine the amount […]
Difference Between Excitation and Absorption
The key difference between excitation and absorption is that excitation is the process of absorbing a photon and moving into a higher energy level whereas absorption is the process of transferring energy from a photon to a certain object. The terms absorption and excitation are useful in the fields of quantum mechanics, analytical chemistry, relativity, […]
Difference Between Neutron and Neutrino
The key difference between neutron and neutrino is that neutrons have a higher mass than neutrinos. Though earlier scientists like Dalton thought that atom is the smallest unit that makes up any substance, they later discovered that there are several other subatomic particles as well. Electrons, protons, and neutrons are the main subatomic particles in […]
