Question

PHYSICS Write briefly about any two historical sundials that still exists in India Differentiate between the properties of solid, liquid and gas based on volume, arrangement of molecules, intermolecular forces, intermolecular compressibility​

Answer 1

Understanding the difference between Solid Liquid and Gas is important as they represent the three different states of matter. As we know, everything around us is matter and it is important to understand the classification of matter; primarily into Solids, Liquids and Gases. A solid can be classified as a substance that is rigid with low intermolecular spacing and high intermolecular forces, that binds all molecules within together. Liquids, on the other hand, are less rigid and flow easily. They usually have properties that enable them to flow from higher areas to lower areas. This is a unique property of liquids when compared to solids. However, there are a few imperfections in solids
