The key difference between internal and external quantum efficiency is that internal quantum efficiency is calculated using the photons that are shinning from inside of the solar cell, whereas external quantum efficiency is calculated using the photons that are shinning from outside of the solar cell. Quantum efficiency or QE is a concept in quantum […]
What is the Difference Between Mobility and Diffusion Coefficient
The key difference between mobility and diffusion coefficient is that mobility is the ability of a charged particle to move due to the effect of an electrical field whereas diffusion coefficient is a constant that describes the relationship between molar flux and the concentration gradient. Mobility is the ability of charged particles to move through […]
What is the Difference Between Equation of State and Activity Coefficient
The key difference between equation of state and activity coefficient is that equation of state can be applied for both liquid and gas phases, whereas the activity coefficient is applied only for gases. Equation of state and activity coefficient are important chemical concepts. Equation of state can be defined as a thermodynamic equation related to […]
What is the Difference Between Adapalene and Benzoyl Peroxide
The key difference between adapalene and benzoyl peroxide is that adapalene is a retinoid, whereas benzoyl peroxide is an antibiotic and skin-peeling agent. Adapalene and benzoyl peroxide are well-known medications in treating acne skin. They both show considerable results, but there are some differences between these two chemicals. CONTENTS 1. Overview and Key Difference 2. What is […]
What is the Difference Between AGM and GEL Batteries
The key difference between AGM and GEL batteries is that AGM batteries allow discharging up to 50%, whereas GEL batteries allow discharging up to 90%, ensuring a long service life. AGM and GEL batteries are types of lead-acid batteries having a lot in common. But there are some differences between AGM and GEL batteries as […]
What is the Difference Between Evaporation and Crystallization
The key difference between evaporation and crystallization is that evaporation is the formation of vapor from a liquid, whereas crystallization is the formation of solid crystals from a liquid. Evaporation and crystallization are physical processes that are opposite of each other. Evaporation is the physical process of conversion of a liquid into its gaseous phase […]
What is the Difference Between Ostwald Theory and Quinonoid Theory
The key difference between Ostwald theory and Quinonoid theory is that Ostwald theory states that the acid-base indicator is either a weak acid or a weak base that only partially ionizes in the solution, whereas Quinonoid theory states that the acid-base indicator occurs in two tautomer forms that change from one form to the other […]
What is the Difference Between Centroid and Centre of Gravity
The key difference between centroid and centre of gravity is that the centroid of a plane figure is the arithmetic mean position of all the points in the figure, whereas the centre of gravity of a material is a point that is useful for a summary description of gravitational interactions. Usually, every object has a […]
What is the Difference Between Kinetic Energy and Temperature
The key difference between kinetic energy and temperature is that kinetic energy refers to the property of a moving object, specifically the work needed to accelerate a body from its resting state, whereas temperature is the thermal energy present in all matter. Kinetic energy and temperature are related terms because the kinetic energy of a […]
What is the Difference Between Einstein and Newton Gravity
The key difference between Einstein and Newton gravity is that Einstein described that gravity is a curvature in a 4-dimensional space-time fabric proportional to object masses, whereas Newton described gravity as a force expressed mutually between two objects in relation to their masses. Einstein gravity and Newton gravity are very important concepts in physical chemistry […]
