plasmas the fourth state of matter

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 'mac..

Voltage or current in simple direct current electric circuits Problems involving Ohm's law Formula for power (rate of energy dissipation) in any resistive circuit element Properties of transistors and their role in electric circuits Electric fields Magnetic fields Direction of a magneti..

The term cytoplasm can be used to describe the matrix of a cell found between its plasma membrane and the nucleus. It encloses various cell organelles and inclusions. The cytoplasm is a semi viscous jelly-like substance. It consists of an aqueous, almost transparent structureless ground s..

The physical meaning of entropy is that entropy is a measure of degree of disorder (or randomness) of a system. The relation between entropy and disorder provides a suitable explanation for entropy change in various processes. The greater the disorder in a system, the higher is the entropy. Obviou..

Water is the only substance that can exist simultaneously in all the three states of matter, i.e., solid, liquid and gaseous on this earth,. A simple experiment shows the existence of all these three states together. Take a glass half packed with ice cubes and co..

Matter is made up of atoms and molecules. These atoms in molecules are in a state of continuous motion. For example, molecules and atoms of a solid can have only vibrational motion, because they are held in their positions by strong intermolecular force..

When the shape, size, appearance or state, of a substance is altered, but its chemical composition remains same a physical change of matter takes place. No new substance is formed. It is usually a change, which is reversible, that is, by reversing the process, the original subst..

Gas is one of the three states of matter - the other two being liquid and solid. A gas differs from a solid and a liquid in a number of ways. A gas fills entire space available to it and therefore it has no definite shape or volum..

Solution is defined as a homogeneous mixture of two or more chemical substances. The state of matter of a solution may be solid, liquid or gas. For example: common salt in water (liquid solution), air (gaseous solution), alloys (solid solution), et..
