This accounts for the fact that a solid keeps its own shape. Solids are usually crystalline. A solid is a crystalline subst..

The States of Matter - Matter occurs in four states: Solid, Liquid, Gas and Plas..

The classification of matter into three different states, namely solid, liquid and gaseous state is termed as the physical classification of matter. Most properties of solid, liquid and gases that can be observed with our sense organs are called as 'macroscopic' ..

Separation of the Constituents of Mixtures The separation of the various constituents of different mixtures depends on the properties of the constituents. Some of these properties are size, density, magnetic nature of particles, solubility, miscibility, differences in boilin..

Matter exists in several phases. If we look at all objects around us, we perceive that some materials have a definite shape and occupy a definite amount of space or volume. We call these materials solids and we can name many objects that are solids. We say that solids have a definite shap..

Is Matter Around us Pure - Impure Substances - Mixtures Impure substances are commonly called mixtures. A mixture is a material containing two or more elements or compounds that are in close contact and are mixed in any proportion. The constituents of mixtures exhibit their individual ..

All around us are substances that are made of matter. Matter has mass and occupies some space. Different kinds of substances are made up of different matter. Matter can be thus classified in many ways. Two basic classifications of matter are based o..
