What is the difference between crystal and grain?

Answer 1

When grains are crystallized they form crystals. We refer crystals as grains because they are basically CRYSTALLIZED grains but they are different in a way because during the formation of crystals the process of crystallization occurs which involves a chemical change and remember chemical change gives a substance new properties so crystals have new properties however its very much like a grain sharing similar properties and the origin of a crystal is a grain. For example a steak is made from chicken though it physically looks different but it is still made from chicken! but has little different properties so we call steak chicken but has different properties even then you wont separate steak from the chicken's category. so you cant separate crystals from grain's category.When you will say grains you will mean simply that minerals joined to make bits called grains and when you say crystals you will mean crystallized grains!
