The key difference between first and second order phase transition is that first order phase transitions depend on the first power of the reactant concentration in a rate equation, whereas second order phase transitions depend on the second power of the concentration in the rate equation. A phase transition is a change of phase of […]

The key difference between refractive index and critical angle is that refractive index is the ratio of the velocity of a light beam in the air to the velocities of the specific medium, whereas critical angle is the angle of incidence at which the angle of refraction is 90 degrees. In optical mechanics, refractive index […]

The key difference between terminal voltage and EMF is that terminal voltage is a closed-circuit voltage, whereas EMF is an open-circuit voltage. Often, the terms EMF (electromotive force) and voltage are mistaken as the same, but these are two different terms. Some people also mistake these terms for electromagnetic fields as well, which is a […]

The key difference between steric and electrostatic stabilization is that steric stabilization is applied to both aqueous and non-aqueous systems, whereas electrostatic stabilization is applied only to aqueous systems. We can combine steric stabilization and electrostatic stabilization to maintain nanoparticle stability in solutions. These types of stabilization are generally provided through ionic surfactants. If we […]

The key difference between Pockels effect and Kerr effect is that in the Pockels effect, the birefringence is proportional to the electric field, whereas, in the Kerr effect, the change of the refractive index is proportional to the square of the field. Pockels effect and Kerr effect are important physical concepts. These two effects are […]

The key difference between delamination and spalling is that delamination occurs by crack extension along a plane parallel to the surface, whereas spalling occurs as a subsequent propagation of the crack through the film. Delamination and spalling are terms related to particle physics. Delamination can be defined as areas having poor or no bonding between […]

The key difference between direct and indirect band gap is that the crystal momentum of electrons and holes is the same in a direct band gap for both the conduction band and the valence band, where an electron can directly emit a photon, whereas indirect band gap has different k-vectors where a photon cannot be […]

The key difference between radiation and electromagnetic radiation is that radiation is energy that travels and spreads out as it goes, whereas electromagnetic radiation is a combination of waves of the electromagnetic field that can propagate through space and can carry electromagnetic radiant energy. The terms radiation and electromagnetic radiation are related to each other […]

The key difference between light energy and heat energy is that light energy is a form of electromagnetic energy, whereas heat energy is a form of kinetic energy composed of random motion of the particles of a material. Although heat and light are both types of energy, they are different from each other. CONTENTS 1. Overview […]

The key difference between voltaic cell and electrolytic cell is that a voltaic cell uses the energy that is released during a spontaneous redox reaction to generate electricity, whereas an electrolytic cell uses the electrical energy from an external source to force a reaction to occur. Voltaic cells or galvanic cells and electrolytic cells are […]
