Haix... Feeling Bored. Guess I shall make notes here...
Erm. Chapt 1 Particulate Model of Matter
All Matter is made up of small discrete particles which are in constant and random motion.
Solid
A Solid has deifinite volume and shape. Its particles are also bonded by strong attractive forces. A Solid's particles are closely packed in regular pattern and thus can only vibrate about their fixed position and cannot moe past each other. Thus, a Solid cannot flow.
Liquid
A Liquid has a deifinite volume but not shape. Its particles are still held together by bonds but they are not as strong as a solids and they can slide past one another. The spaces between the particles are also bigger and thus the Liquid can flow and take the shape of the container that it fits in. A liquid however is still held by atrractive bonds and has deifinite volume.
Gas
A gas has no definite volume or shape. Its particles has almost completely no bonds and moves about at high speeds. The particles spread out as far and as fast as possible colliding with one another and the container as fast as they can. Thus, a gas has no definite volume or shape but simply take the volume of its container. A gas will flow very quickly as the particles move at high speeds.
