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

7 Difference Between Embryo And Zygote

What Is a Zygote? Zygote is a single cell that results from the fertilization of an egg by a sperm. It is also known as a fertilized egg or an embryo. The zygote divides to form a ball of cells called a blastocyst, which in turn divides to form the baby and other structures in … Read more

Difference Between Valence Bond Theory And Molecular Orbital Theory

A molecular orbital is an orbital or wave function of a molecule’s electron. The function may be used to calculate the probability of finding an electron within a specified space or to predict the molecule’s chemical and physical properties. Robert Mulliken introduced the term “orbital” in 1932 to describe a one-electron orbital wave function. Electrons around a molecule can … Read more

Transgenic Animals: Methods Of Production, Examples & Applications

What are Transgenic Animals? Transgenic means that one or more DNA sequences from another species have been introduced by artificial means. Animals usually are made transgenic by having a small sequence of foreign DNA injected into a fertilized egg or developing embryo. Transgenic animals are animals which have been genetically transformed by splicing and inserting … Read more
