The key difference between molecular and metallic hydrogen is that molecular hydrogen has gaseous properties, whereas metallic hydrogen has metallic properties similar to that of alkali metals. Hydrogen is the first chemical element in the periodic table of elements. It usually occurs in the gaseous state as dihydrogen molecule. In this state, hydrogen is named […]

Difference Between Myxomycota and Eumycota
The key difference between Myxomycota and eumycota is that Myxomycota consists of fungi-like slime molds which lack cell walls in the vegetative state while eumycota consists of true fungi which are filamentous eukaryotic heterotrophic microorganisms consisting rigid cell walls. Myxomycota and eumycota are two major divisions of organisms. Myxomycota belongs to Kingdom Protista while eumycota […]
Difference Between Dielectric Constant and Relative Permittivity
The key difference between dielectric constant and relative permittivity is that dielectric constant refers to the relative permittivity of a dielectric substance whereas relative permittivity refers to the permittivity of a substance in comparison to the permittivity of a vacuum. The terms permittivity and dielectric constant are used in capacitor technology; for example, using capacitors […]
Difference Between Polysiloxane and Polydimethylsiloxane
The key difference between polysiloxane and polydimethylsiloxane is that polysiloxane has silicon atoms attached to two oxygen atoms and two alkyl groups, whereas polydimethylsiloxane has silicon atoms attached to two oxygen atoms and two methyl groups. Both polysiloxane and polydimethylsiloxane are important silicone polymer materials. They have different chemical and physical properties as well as […]
Difference Between Obligate Aerobes and Obligate Anaerobes
The key difference between obligate aerobes and obligate anaerobes is that obligate aerobes cannot live without the presence of oxygen while obligate anaerobes cannot live in the presence of oxygen. Microorganisms show great diversity since they are present everywhere. They react differently to molecular oxygen. There are six major groups of microorganisms based on the […]
Difference Between Isomerization and Hydroisomerization
The key difference between isomerization and hydroisomerization is that isomerization refers to the conversion of the structure of one compound to its isomeric structure whereas hydroisomerization is the conversion of one isomeric form into another of alkane hydrocarbons via an alkene intermediate Isomers are chemical compounds having the same chemical formula but different chemical structures. […]
Difference Between Flash Point and Auto Ignition Temperature
The key difference between flash point and auto ignition temperature is that flash point determines the lowest temperature at which vapour of a material starts ignition in the presence of an ignition source whereas auto ignition temperature is the lowest temperature at which a material can start ignition spontaneously. Both flash point and auto ignition […]
Difference Between Codominance and Multiple Alleles
The key difference between codominance and multiple alleles is that codominance is expressing the effects of both alleles independently, without blending in the heterozygous state, while multiple alleles refer to the state of a trait that has more than two different alleles. Generally, each gene comes with two different alleles. One is a dominant allele […]
Difference Between Radioactive and Nonradioactive Probes
The key difference between radioactive and nonradioactive probes is that radioactive probes are single-stranded DNA or RNA sequences that are labeled with radioactive isotopes while nonradioactive probes are single-stranded DNA or RNA sequences that are labeled with a chemical tag or a fluorescent tag. Nucleic acid hybridization is an important technique in molecular biology, especially […]
Difference Between Molecular Sieve and Silica Gel
The key difference between molecular sieve and silica gel is that a molecular sieve is a material containing pores of similar size, whereas silica gel is a substance can be used to prepare a porous material with pores of different sizes. Both molecular sieve and silica gel are important materials in chemical separations. They are […]
