The key difference between cyclotron and betatron is that cyclotron uses a spiral path, whereas betatron uses a circular path for accelerating charged particles. Cyclotron and betatron are two types of particle accelerators. Cyclotron is the earliest form of the accelerator, while betatron is modern compared to it. Both these systems use magnetic fields and […]
Difference Between Valence Shell and Penultimate Shell
The key difference between valence shell and penultimate shell is that valence shell is the outermost electron-containing shell of an atom, whereas penultimate shell is the shell that is inner to the outermost electron-containing shell. The terms valence shell and penultimate shell are used mainly in general chemistry when determining the electron composition of a […]
Difference Between Configurational Entropy and Thermal Entropy
The key difference between configurational entropy and thermal entropy is that configurational entropy refers to the work done without an exchange in temperature, whereas thermal entropy refers to the work done with the exchange in temperature. In this, entropy is a measure of the randomness of a thermodynamic system. An increase in the randomness refers […]
Difference Between Klebsiella pneumoniae and Streptococcus pneumoniae
The key difference between Klebsiella pneumoniae and Streptococcus pneumoniae is that Klebsiella pneumoniae is gram-negative rod-shaped bacterium while Streptococcus pneumoniae are gram-positive, nonmotile, and nonsporulating oval or spherical shaped bacterium. Both Klebsiella pneumoniae and Streptococcus pneumoniae are two different bacteria that cause pneumonia, and several other types of infections. Both types of bacteria are facultative […]
Difference Between Prepolymer and Oligomer
The key difference between prepolymer and oligomer is that a prepolymer is an intermediate of a polymerization reaction, whereas an oligomer is a polymer material composed of comparatively a few monomer units. A polymer is a chemical substance consisting of large molecules made from many smaller and simpler molecules, known as monomers. Both prepolymers and […]
Difference Between Detergent and Chaotropic Agent
The key difference between detergent and chaotropic agent is that detergents can denature proteins by solubilizing hydrophobic groups, whereas chaotropic agents can denature proteins by weakening hydrophobic effect. Detergents are surfactants. These compounds have cleansing properties. The main action of these compounds is to denature protein compounds. However, there are non-detergent compounds that can denature […]
Difference Between Bacillus and Clostridium
The key difference between Bacillus and Clostridium is that Bacillus is a genus of gram-positive bacteria that grows under aerobic conditions, produces oblong endospores and secretes catalase while Clostridium is a genus of gram-positive bacteria that grows under anaerobic conditions, produces bottle-shaped endospores and does not secrete catalase. Clostridium and Bacillus are two genera belonging […]
Difference Between Carburizing and Carbonitriding
The key difference between carburizing and carbonitriding is that carburizing is the process of hardening a steel surface using carbon, whereas carbonitriding is the process of hardening a steel surface using carbon and nitrogen. Hardening is the industrial process of increasing the hardness of a metal such as steel. Surface hardening of steel can be […]
Difference Between Fluorapatite and Hydroxyapatite
The key difference between fluorapatite and hydroxyapatite is that fluorapatite contains calcium phosphate in association with fluoride groups, whereas hydroxyapatite contains calcium phosphate in association with hydroxide groups. Both fluorapatite and hydroxyapatite are phosphate-containing minerals. These are calcium phosphate forms containing different associated groups. That is, fluorapatite contains fluorine groups, while hydroxyapatite contains hydroxide groups. […]
Difference Between Azotobacter and Azospirillum
The key difference between Azotobacter and Azospirillum is that Azotobacter is a genus of bacteria that are mainly aerobic and endophytic diazotrophs. Meanwhile, Azospirillum is a genus of plant growth-promoting bacteria that are microaerophilic and surface-colonizing bacteria. Azotobacter and Azospirillum are two bacterial genera that are important as nitrogen fixers in the soil. They are […]
