It is easy to define physical chemistry because the name is self-explanatory. The accepted definition of physical chemistry is, it is a field of study that incorporates physics principles, theories, and techniques into chemistry to understand the properties of chemical substances better. The nature ...
In the chapter on the properties of gases, normal temperature and pressure are defined as I5掳C. and 760 mm. of mercury, although later on in the same chapter the more usual o掳 C. and 760 mm. are frequently used. The definition of atomic weight as obtainable from the experimental ...
We have seen that isotopes differ in mass number. The mass number has very little bearing on chemical reactions; therefore thereactivityand chemical reactions of an element's different isotopes are almost identical. The physical properties of atoms, however, do depend on mass. This enables isotopes...

Matter can be classified in various ways according to its structure, behaviours and physical and chemical properties. The main classifications of matter include the categories element and compound, either of which may also be called a substance (which is a less specific term), and mixture, of wh...

This is the definition of physical change in chemistry, along with examples of types of physical changes.
Properties of Plasma In a sense, plasma is like a gas in that it assumes the shape and volume of its container. However, plasma isn't as free as gas because its particles are electrically charged. Opposite charges attract each other, often causing plasma to maintain a general shape or flo...
