The key difference between pyrolysis and gasification is that pyrolysis is done in the absence of air while gasification is done in the presence of air. Pyrolysis and gasification are two important processes that are used to decompose materials. Both these processes are different from combustion because the combustion is carried out in the presence […]
Difference Between Galvanic Series and Electrochemical Series
The key difference between galvanic series and electrochemical series is that galvanic series shows the order of nobility of metals and semi-metals, whereas electrochemical series shows the order of standard electrode potentials of chemical elements. The galvanic series and electrochemical series are two different lists which shows an arrangement of chemical elements according to their […]
Difference Between Chemisorption and Physisorption
The key difference between chemisorption and physisorption is that chemisorption is a type of adsorption in which the adsorbed substance is held by chemical bonds whereas physisorption is a type of adsorption in which the adsorbed substance is held by intermolecular forces. Chemisorption and physisorption are generally important chemical concepts we can use to describe […]
Difference Between Fermi Energy and Fermi Level
The key difference between Fermi energy and Fermi level is that Fermi energy is the energy of fermi level, whereas Fermi level is a measure of least tightly bound electrons within a solid. The terms fermi energy and Fermi level are named after the physicist Enrico Fermi. Fermi energy is the value of energy for a […]
Difference Between Lead Acid Battery and Alkaline Battery
The key difference between lead acid battery and alkaline battery is that lead acid batteries are rechargeable while alkaline batteries are mostly non-rechargeable. A battery is a device that has one or more electrochemical cells. It has external connections we can connect to power devices such as smartphones, flashlights, etc. Moreover, it has a positive […]
Difference Between Ideal Gas Law and Real Gas Law
The key difference between ideal gas law and real gas law is that ideal gas law describes the behaviour of a theoretical gas, whereas real gas law describes the behaviour of actually occurring gases in the universe. An ideal gas is a theoretical gas whose randomly moving gas particles have completely elastic collisions and no […]
Difference Between Sacrificial Anode and Impressed Current
The key difference between sacrificial anode and impressed current is that in sacrificial anodes, a metal or alloy is placed in order to act as the anode instead of the metal to be protected whereas, in impressed current method, a DC current is provided to the metal to be protected in order to make it […]
Difference Between Single Electrode Potential and Standard Electrode Potential
The key difference between single electrode potential and standard electrode potential is that single electrode potential is the potential of a single electrode in an electrochemical cell whereas standard electrode potential is the potential difference between two electrodes at standard conditions. An electrochemical cell is a device that can either generate electricity using chemical reactions […]
Difference Between QED and QCD
The key difference between QED and QCD is that QED describes the interactions of charged particles with the electromagnetic field, whereas QCD describes the interactions between quarks and gluons. QED is quantum electrodynamics whereas QCD is quantum chromodynamics. Both these terms explain the behaviour of small scale particles such as subatomic particles. CONTENTS 1. Overview […]
Difference Between Anodic and Cathodic Protection
The key difference between anodic and cathodic protection is that in anodic protection, the surface to be protected acts as the anode whereas, in cathodic protection, the surface to be protected acts as the cathode. Anodic and cathodic protection are two electrochemical processes we use to prevent surfaces from corrosion or rusting. In an electrochemical […]
