Isobutylbenzene: Formula, Structure, Properties & Uses

Isobutylbenzene, also known as 2-methyl-1-phenylpropane, is an organic compound with the chemical formula C10H14. It is classified as an alkylbenzene, which means it is derived from benzene by replacing one of the hydrogen atoms with an alkyl group. In the case of isobutylbenzene, the alkyl group is an isobutyl group (a branched chain of four … Read more

Fick’s First Law: Definition, Derivation And Application

What is Fick’s law of diffusion? Fick’s law of diffusion explains the diffusion process (movement of molecules from higher concentration to lower concentration region). In 1855, Adolf Fick described the Fick’s Law of Diffusion. A diffusion process that obeys Fick’s laws is called normal diffusion or Fickian diffusion. A diffusion process that does NOT obey Fick’s laws … Read more

Modulus of Rigidity: Definition And Equation

Modulus of rigidity is the ratio of shear stress to the corresponding shear strain within the proportional limit of a material. Modulus of rigidity is also known as shear modulus and rigidity modulus values of materials are determined by torsional tests. Modulus of rigidity formulas are G = τ/γ and G = E/(2(1+v)). Here τ … Read more

What Is Poisson’s Ratio?

Poisson’s Ratio is defined as the ratio between the lateral contraction (expansion) strain to the longitudinal extension (contraction) strain when an object is subjected to an external tensile (compressive) force along its longitudinal axis. When a solid bar is subjected to tensile force along its longitudinal axis, the length of the bar increases in the direction of application of … Read more
