In mass transfer, flux is the amount of mass flowing through a unit area per unit time. Flux is represented by the symbol "J" and can be either molar flux (J) or mass flux (N). Molar flux (J) is the amount of moles of a component flowing through a unit area per unit time, while mass flux (N) is the amount of mass of a component flowing through a unit area per unit time. The key difference between the two is that molar flux is expressed in moles per unit area per unit time, while mass flux is expressed in kilograms per unit area per unit time.

RafaIn mass transfer, flux J is the amount of mass transferred per unit area per unit time, while concentration gradient N is the driving force for mass transfer. J is directly proportional to N according to Fick's first law of diffusion, which relates the flux to the concentration gradient.

What is mass transfer?
Mass transfer is the movement of substances from one place to another, often between phases such as gas, liquid, or solid. It can involve diffusion, convection, or mass transfer through a phase boundary, and is important in various engineering and natural processes such as chemical reactions, separation processes, and biological systems.
What is the mass defect?
If you add the exact mass of the protons, neutrons, and electrons in an atom you do not get the exact atomic mass of the isotope. The diference is called the mass defect. The difference between the mass of the atomic nucleus and the sum of the masses of the particles within the nucleus is known as the mass defect.
What term describes the tiny difference in mass between the products and reactants of a nuclear change?
The term that describes the tiny difference in mass between the products and reactants of a nuclear change is "mass defect." This difference in mass is converted into energy according to Einstein's famous equation E=mc^2, which explains the principle behind nuclear reactions.
How is the mass defect determined?
The mass of a nucleus is subtracted from the sum of the masses of its individual components.
Mass by difference?
Mass by difference is a method used in analytical chemistry to determine the mass of a component in a mixture by weighing the entire mixture before and after the component of interest is removed. The mass of the component is then calculated as the difference between the two measurements. This technique is commonly used when the component of interest cannot be easily separated or directly measured.
