classification of matter substances

Ferromagnetism, like paramagnetism, occurs in materials in which atoms have permanent magnetic dipole moments. The strong interaction between neighboring atomic dipole moments keeps them aligned even when the external magnetic field is removed. Some important properties are: These substances..

Paramagnetic substance are attracted by a magnet very feebly. In a sample of a paramagnetic material, the atomic dipole moments initially are randomly oriented in space. When an external field is applied, the dipoles rotate into alignment with field as shown The vector sum of the individu..

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 classificationsh..

All matter can be broadly divided into two major groups "Pure" and "Impure". The term 'purity' has quite a different meaning in chemistry than in our day-to-day life. Normally when we refer to pure water, pure milk, etc., what is implied is that the water, milk etc., are free from h..

All matter can be broadly divided into two major groups "Pure" and "Impure". The term 'purity' has quite a different meaning in chemistry than in our day-to-day life. Normally when we refer to pure water, pure milk, etc., what is implied is that the water, milk etc., are free from harmful..

"Impure substances are commonly called mixtures." The constituents of a mixture may be elements, compounds, or both. These substances may be present in any proportion and exhibit their individual properties. Mixtures can be homogeneous or heterogeneous. A homogeneous mixture has..

'. We may note that the specific heat of water is the highest. It requires nearly 4200 Joules of heat energy to increase the temperature of 1 Kg of water by 1K. Infact, water has one of the highest specific heats of all matter. Liquid ammonia with a specific heat of 5040 J/Kg/Kelvin is on..

Pure Substances The distinctive features of pure substances are: A pure substance is composed of the same kind of particles e.g. hydrogen, oxygen, water, sodium chloride, etc. A pure substance is homogeneous, irrespective of its origin or method of p..

A solid has certain characteristics: According to modern theory, the molecules of a solid are fixed in relation to each other. They vibrate in place, but do not wander around. This accounts for the fact that a solid keeps its own shape. Solids are usually crystalline. A solid is a crystalline ..

Summary Matter is anything that occupies space and has mass Element is a pure substance, which can neither be decomposed nor built from simpler substances by any physical or chemical means. It contains only one kind of atom. Broadly speaking, elements can be..
