Describe the three stage of matter that are typically encountered on a daily basis. How are they different?
The three stages of matter that are typically encountered on daily basis are solid, liquid and gas. In a solid, the particles are packed closely together. The forces between the particles are strong enough that the particles cannot move freely; they can only vibrate about their positions. As a result, the solids will have definite shape and definite volume. There are crystalline and amorphous solids. Solids transform into liquids through melting and liquids change into solids through freezing. A solid can directly change into gas through sublimation. A liquid is a fluid that confirms to the shape of its container but that retains a nearly constant volume independent of pressure. The intermolecular forces in a liquid are important, but the molecules have enough energy to move around. As a result, the liquid is mobile. It is not definite in shape, but rather conforms to the shape of its container. The volume of the liquid is generally greater than the corresponding solid. The process of liquid changing into gas is called evaporation.
