Lots of good illustrations. Polymer Planet is a very elementary introduction to polymers for K Developed by the International Union of Crystallography, these have been available as printed "teaching pamphlets" for many years, and are are now freely available on the Web for the use of instructors and individuals. Part of the Chem1 Virtual Textbook Changes of state: vapor pressure, boiling, phase maps - Vapor pressure and the stabiity of a phase, condensation, boiling and nucleation, phase diagrams of representative substances, phases at the extremes of temperature and pressure, helium phase weirdness. Energy, enthalpy, and the First Law - a nice set of tutorials from Purdue U. Watters presents some nice simulations with good expanatory material, but navigation within the site is awkward. A PowerPoint version is available for teachers. Very readable and interesting, set at the "Scientific American" level and suitable for high school and introductory college courses. It uses examples of nanotechnology and advanced materials to explore science and engineering concepts mainly at the college level, but there are also sections for K Why Study Chemistry? Many of the pages include applets that require a Java-enabled browser. Chemistry Topics. StudyOrgo - offers a variety of materials for learning organic chemistry. Illinois - Springfield.
There are many interactive examples, and the materials may be downloaded for installation on a local server. Physics - this elegantly-done site covers modern physics and its applications to such uses as microwave ovens, catscans, etc. It is intended for second-year students.
The second law This qualitative presentation by Frank Lambert will be useful to students and others having limited scientific backgrounds, and to teachers who are seeking ways to make the subject more meaningful.
But before diving into the areas of measurement and reactions, be sure to get a solid ground of understanding with Chemical Bonding and the Periodic Table and Trends.
A PowerPoint version is available for teachers.
Also, from the knowledge of chemical properties of substances, it is possible to predict the kind of chemical reactions that will occur between different substances under certain conditions, and the new substances that will be formed from such reactions. StudyOrgo - offers a variety of materials for learning organic chemistry. Fusion Energy Resources - a variety of information and educational resources on nuclear fusion from the General Atomics fusion group. You may have been observing this, but may not have known that the cause of the brown color is a chemical reaction which takes place between the oxygen of the air and some chemical substances in the apple and the other produce. It is intended for second-year students. Read more on Why Study Chemistry here. College students in their first year will also find the tutorials useful for the first two semester chemistry work. See some of his other organic sites.
Physical chemistry Intermolecular forces - a multi-part tutorial covering the principal kinds of weak interactions between molecules with many examples and comparative data. Organic Chemistry Help Immediately "OCHeM" - this site offers a wide variety of materials: tutorials, Web-flashcards, practice questions, lab information, and practice exams.
Energy, enthalpy, and the First Law - a nice set of tutorials from Purdue U. It looks into the chemical changes that occur between different substances and from the knowledge of the properties of the substances involved, it can explain what happened.
Water and hydrogen bonding - First-year-level treatment the "anomalous" properties of water, structure of liquid water and of ice, hydrogen bonding in small molecules and in biopolymers.
Branches of chemistry
Everything around us is a chemical substance which can undergo reactions or change with others. Kinetics and mechanisms Chemical kinetics and dynamics - A comprehensive treatment of rates of reaction, rate laws, activation energy, and reaction mechansms. The knowledge of this chemistry will not only enable you to understand the chemical reaction involved, but also to prevent it from happening if you don't want the brown color, or to promote it if you like it. You may have been observing this, but may not have known that the cause of the brown color is a chemical reaction which takes place between the oxygen of the air and some chemical substances in the apple and the other produce. Chemical kinetics simulators - this site by Gary Bertrand allows you to simulate first-, second-, and third order kinetics and to deduce the rate constant and half life. The ingredients are mixed up in certain proportions and cooked together to produce the tasty food. Matter is anything that has mass and takes up space. Heyes of Oxford offers an exceptionally complete coverage of elementary crystallography and the representation of crystal structures. Water and hydrogen bonding - First-year-level treatment the "anomalous" properties of water, structure of liquid water and of ice, hydrogen bonding in small molecules and in biopolymers. Part of the Chem1 Virtual Textbook Liquids and their interfaces - An introduction to liquids: viscosity, surface tension, interfacial effects including wetting, capillary rise, and bubble formation. Polymer Chemistry Hypertext - this somewhat advanced material for a second-semester polymer course is organized by concept. In Chemistry, thorough investigation of the properties of matter has allowed us to learn what gases create the air, how electricity can be used to power a computer, and what a water molecule looks like. Detailed instructions are provided that serve as the basis for a number of exploration exercises. It provides explanations to many physical and biological phenomena. Virtual Textbook of Organic Chemistry - a nicely designed, comprehensive site with tutorials and practice problems.
