It is critical to understand the properties of the materials we use and manipulate. It is critical to determine whether or not a substance is an electrical conductor. You can’t build wire and cables to transmit electricity otherwise. You must determine whether anything is combustible or combustion supporter. You must know whether something is water […]

Empirical formula : To define the formula of empirical, we can say that the empirical formula of a compound is a ratio of atoms present in a molecule (or ion). An empirical formula is a simple whole-number ratio of the number of atoms of each type. If this equation is not a whole number it

Introduction Due to the large number of elements and chemicals existing in our environment, we have an excellent opportunity to learn about their qualities. It is necessary to investigate the many qualities of such stuff because this will make it easier to comprehend the nature and activity of these substances in the future. The determination

Ores are a mixture of minerals and various other particles that need to be processed to extract minerals in their pure form. Also known as enrichment, the concentration of ores is the method of removing impurities and other unwanted particles from the ore. The removal method of the gangue particles or the unwanted particles depends

A gas’s density In general, we can define it as a substance’s mass per unit volume when subjected to specific temperature and pressure conditions. In addition, the density of a gas is equal to the product of its mass divided by its volume. Furthermore, if you know a gas’s density, you can use that information

Municipal solid waste management systems are built around the collection and disposal of garbage and other waste.  The primary goal of a waste collection strategy is to collect, in a timely and cost-effective manner, as much correctly source separate waste as possible, in order to make the subsequent waste sorting and or treatment stage as

Temperature is a critical physical quantity that shows how hot or cold something is. Temperature is typically stated as a numerical value on a standard scale. The same temperature has different readings on the three temperature scales – Fahrenheit, Celsius, and Kelvin.  Formula For Converting Celsius to Kelvin  In physics, the Celsius scale is most

In the field of chemistry, a mole is defined as the amount of a substance that contains exactly 6.02214076 x 1023 of the substance’s ‘elementary entities,’ which are defined as the atoms, molecules, and ions that make up the substance. In mathematics, the number 6.02214076 x 1023 is referred to as the Avogadro constant, and

Sublimation is the process by which a substance changes directly from the solid to the gas state without passing through the liquid state. When a substance’s triple point in its phase diagram is reached, which corresponds to the lowest pressure at which the substance can exist as a liquid, sublimation happens as an endothermic process.

Introduction to Avagadro’s Number The term “Avogadro’s number” is firstly described by a physician in French named  “Jean Baptiste Perrin”. Based on his research on Brownian motion, Perrin estimated its approx value in 1909. However, “Josef Loschmidt” became the first to estimate the correct value of particles in a given volume of any substance.  Avogadro’s
