The key difference between anisotropy and isotropy is that anisotropy is directionally dependent whereas isotropy is directionally independent. The words isotropy and anisotropy are useful in various fields. According to where we use it, the meaning may be slightly different. However, the fundamental concept behind these two words is similar and independent from where we […]
Difference Between Adhesion and Cohesion
The key difference between adhesion and cohesion is that adhesion is the attraction between substances or molecules that are not similar whereas cohesion is the attraction between the molecules or substances that are similar. There are various phenomena to explain the things we observe in our daily lives. Although sometimes we do not focus on […]
Difference Between Closed System and Open System
The key difference between closed system and open system is that in a closed system, the matter does not exchange with the surrounding but, the energy exchanges with the surrounding whereas in an open system, both matter and energy exchanges with the surrounding. For the purpose of chemistry, we can divide the universe into two […]
Difference Between Electrochemical Cell and Galvanic Cell
The key difference between electrochemical cell and galvanic cell is that most electrochemical cells tend to convert electrical energy into chemical energy, whereas galvanic cells tend to convert chemical energy into electrical energy. Oxidation and reduction reactions play an important role in electrochemistry. In an oxidation-reduction reaction, electrons are transferred from one reactant to another. […]
Difference Between Enthalpy and Entropy
The key difference between enthalpy and entropy is that enthalpy is the heat transfer taking place in a constant pressure whereas entropy gives an idea of the randomness of a system. For the study purposes in chemistry, we divide the universe into two as a system and surrounding. At any time, the part we are […]
Difference Between Equilibrium and Steady State
The key difference between equilibrium and steady state is that in equilibrium, the concentrations of all components are being held constant whereas, in steady state, only some components are kept constant. When one or more reactants are converted to products, they may go through different modifications and energy changes. The chemical bonds in the reactants […]
Difference Between Reaction Rate and Rate Constant
The key difference between reaction rate and rate constant is that reaction rate is the speed at which reactants are converted into products whereas rate constant is a coefficient of proportionality relating the rate of a chemical reaction at a given temperature to the concentration of the reactant or to the product of the concentrations […]
Difference Between Adiabatic and Polytropic
The key difference between adiabatic and polytropic processes is that in adiabatic processes no heat transfer occurs whereas in polytropic processes heat transfer occurs. In chemistry, we divide the universe into two parts. The part we are going to study is “a system”, and the rest is “the surrounding”. A system can be an organism, […]
Difference Between Adiabatic and Isentropic Processes
The key difference between Adiabatic and isentropic processes is that adiabatic processes can be either reversible or irreversible, while an isentropic process is a reversible process. In chemistry, we divide the universe into two parts. The part we are interested in is a system, and the rest is the surrounding. A system can be an […]
Difference Between Work and Heat
The key difference between work and heat is that work is the ordered motion in one direction whereas heat is the random motion of molecules. Work and heat are the two most important concepts of thermodynamics. Work and heat are highly interrelated to each other but they are not quite the same. The quest to […]
