1. Mass is a property of a physical body and it is also given as a measure of resistance to acceleration for a body when a net force is applied. In simple words, mass is essentially "how much stuff" is in an object. Kilogram is the SI unit of m...
The letter µ in chemistry In chemistry, µ refers to the elementary particles muon and antimuon. A muon is similar to anelectron. However, its mass is about 207 times the mass of the electron. It is created when an electron collides with its antiparticle positron (e+). The collision...
An assay is a process of analyzing a substance to determine its composition or quality. Three techniques—fire assay, wet chemistry, and instrumental analysis—are primarily used to analyze and determine the purity of metals. Assays are used to meet the delivery requirements for futures contracts....
