states of matter fourth grade

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 super cooled ..

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..

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..

A solid has a definite characteristic shape tends to resist deformation of its shape is relatively non compressible For example, diamond Solids can be classified as: Crystalline Amorphous In a crystalline substance the solid is characterised by a very definite, well-defined externa..

Introduction - Today the fact that all matter is made up of atoms is universally accepted. Realisation of the atomic constituents of matter began in 1828 when Scottish botanist Robert Brown observed a random ceaseless motion of pollen grains suspended in a liquid. Many macroscop..

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..
