Understanding Substance substance is anything that occupies space and has massa.Apakah objects need a place? Eg available water in the glass. Pour the water into the canister. Does the water occupies cans? It turned out that the water needs a place or container. Furthermore, if the water in the container was weighed proved to have mass. Similarly, the air was also occupies space and has mass.
Around you there are things that you can be grouped into three states of matter. Some objects such as metal, wood, aluminum including solids. Water, including liquid petroleum, whereas LPG,
including substance gas.Pada air principle, there are three types of states of matter, namely:
1. The solid,
Solids have a fixed volume and shape properties. The
shape is fixed because the particles in solids are close together,
arranged orderly and attractive forces between the particles have very
powerful. Volume remains due to the solid particles can move and rotate at any position.
2. Liquid
Liquid has the properties of arbitrary shape and fixed volume. The
shape change due to the particles in the liquid adjacent but tenuous,
arranged orderly, attractive force between the particles is rather weak.
Fixed volume because the particles in a liquid move easily but can not leave the group.
3. Substance gas.
Gas substances have properties changing shape and volume changes. Changing
shape due to substance gas partikelpartikel apart, irregularly
arranged, attractive force between the particles is very weak. Volume change due to the particles in a gas substance can move freely leave the group.
