Chemistry matter and change california pdf
Chemistry. Matter and Change - PDF Free DownloadWhile this simple definition is easily applied, the way people view matter is often broken down into two characteristic length scales: the macroscopic and the microscopic. Matter is anything that has mass and volume takes up space. For most common objects that we deal with every day, it is fairly simple to demonstrate that they have mass and take up space. You might be able to imagine, however, the difficulty for people several hundred years ago to demonstrate that air has mass and volume. Air and all other gases are invisible to the eye, have very small masses compared to equal amounts of solids and liquids, and are quite easy to compress change volume.

Table of Contents
In classical physics and general chemistry, matter is any substance that has mass and takes up space by having volume. However it does not include massless particles such as photons , or other energy phenomena or waves such as light or sound. These include classical everyday phases such as solid , liquid , and gas — for example water exists as ice, liquid water, and gaseous steam — but other states are possible, including plasma , Bose—Einstein condensates , fermionic condensates , and quark—gluon plasma. Usually atoms can be imagined as a nucleus of protons and neutrons , and a surrounding "cloud" of orbiting electrons which "take up space". In the Standard Model of particle physics , matter is not a fundamental concept because the elementary constituents of atoms are quantum entities which do not have an inherent "size" or " volume " in any everyday sense of the word. Due to the exclusion principle and other fundamental interactions , some " point particles " known as fermions quarks , leptons , and many composites and atoms, are effectively forced to keep a distance from other particles under everyday conditions; this creates the property of matter which appears to us as matter taking up space.
