physical properties of plasma

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 shape and a de..

All material is made from small moving particles called atoms. Materials can be solid, liquid or gaseous, depending upon the arrangement and freedom of movement of these particles. Diffusion is the movement of particles from a place of high concentration to a place of lower concentration on..

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..

Plasma are much like gases except that their constituent particles have become electrically charged, and their behavior in consequence depends strongly upon electromagnetic forces. Most of the matter in the universe is in the plasma state. A fluorescent tube contains plasm..

When a bar magnet is suspended freely, it always comes to rest in a north-south direction. This property is used in the construction of a mariner's compass. ..

A magnet attracts magnetic substances like iron, steel etc. This property is used to separate iron from a mixture, to remove iron filings from the eye et..

Properties of Matter - 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 crystallin..

On observing waves, it may be observed that they travel with a definite speed through a uniform medium. If we watch a particular spot, we find that the waves pass that spot at regular intervals of time. The following definitions help in describing wave motio..
