Chem Matter and Change Textbooks :: Free Homework Help and Answers :: SladerChange is happening all around us all of the time. Just as chemists have classified elements and compounds, they have also classified types of changes. Changes are either classified as physical or chemical changes. Chemists learn a lot about the nature of matter by studying the changes that matter can undergo. Chemists make a distinction between two different types of changes that they study - physical changes and chemical changes. Physical changes are changes in which no bonds are broken or formed. This means that the same types of compounds or elements that were there at the beginning of the change are there at the end of the change.

Chemistry. Matter and Change
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. For much of the history of the natural sciences people have contemplated the exact nature of matter.
