plasmas the fourth state of matter

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..

Types of Solutions 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), etc. The c..

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 subst..

According to the dynamic particle model all states of matter are made up of tiny particles and matter as a result is an aggregation of very small particles. Nevertheless, the state of aggregation of particles is different in different substances. Some charac..

Characteristics of Particles of Matter - According to the dynamic particle model all states of matter are made up of tiny particles and matter as a result is an aggregation of very small particles. Nevertheless, the state of aggregation of particles..

Effect of Pressure on Matter - Pressure has little effect on the state of solids and liquids as the inter-particle distance is already minimized in these situations. However, the effect of pressure in case of gases is considerabl..

Question 1 - Question: A substance has a definite volume but no definite shape. State whether this substance is a solid, liquid or a gas. Answer: The substance is a liquid. It has a definite volume but no definite shape and takes the shape of the container in which it is plac..

This theory explains the physical properties of matter in terms of motion of its molecules. According to this theory, every substance (solid, liquid or gas) consists of a large number of minute particles called molecules . A molecule may be defined as the smallest particle of a substance ..

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 divided into metals, non-me..
