plasmas the fourth state of matter

The fourth state called plasma refers to the super heated gaseous state. This is a mixture of electrons and positively charged ions with unusual properties. It is found at extremely high temperatures such as interiors of the sun or stars. Astronomers reveal t..

Summary Matter - anything which has mass, occupies space and can be perceived by our senses. Law of conservation of matter - matter can neither be created nor destroyed. The states of matter are solid, liquid gas, plasma and sup..

Solids Liquids Gases Particles are very closely packed thus rigid Particles are loosely packed thus can flow Particles are very loosely packed and can flow Voids are extremely small thus incompressible Voids are relatively larger thus slightly compressible Voids are v..

The particles present in matter are not stationary, but have a tendency to acquire motion. In fact they are in a state of continuous motion. The rate of movement of the particles is directly proportional to the thermal energy of the particl..

Depending on the conditions of temperature and pressure, matter can exist in any of the three main states i.e., solid, liquid or gas. Matter can be inter-converted from one state to the other by the addition or removal of heat energy. All the three stat..

Effect of Temperature and Pressure on States of Matter - When we heat a solid, we add energy to the system increasing the vibration of the particles. Eventually these particles break free from their binding forces and melt. The normal melting point of a crystal is the temperatur..

When we heat a solid, we add energy to the system increasing the vibration of the particles. Eventually these particles break free from their binding forces and melt. The normal melting point of a crystal is the temperature at which it melts under one atmospheric pressure. Increase in pressur..

Matter and Materials - 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..
