Bosons and Fermions
By definition, bosons are particles which obey Bose-Einstein statistics: when one swaps two bosons, the wavefunction of the system is unchanged.
Fermions, on the other hand, obey Fermi-Dirac statistics and the Pauli exclusion principle: two fermions cannot occupy the same quantum state as each other, resulting in a "rigidity" or "stiffness" of matter which includes fermions. Thus fermions are sometimes said to be the constituents of matter, while bosons are said to be the particles that transmit interactions (force carriers), or the constituents of radiation.
ADD:Some people divide matter into pure substances and mixtures. Pure substances are elements and compounds. Mixtures include homogeneous and heterogeneous mixtures. Some people divide matter into homogeneous matter and heterogeneous matter. Homogeneous matter includes pure substances and homogeneous mixtures (solutions). Heterogeneous matter is heterogeneous mixtures.
The two ways of classifing matter are (1) On the basis of physical state as a solid, liquid or gas. (2) On the basis of chemical constitution as an element, compound or mixture.
1. By its physical state - solid, liquid or gas
2. By its chemical constitution - element, compound or mixture
chemical
A tree has mass and volume, therefore it is matter.
MATTER
Generally there are two types of physical quantities. One without direction known as scalars other with direction known as vectors. While there are other physical quantities as well that cannot be classified under the two above mentioned categories, they are tensors, matrices, spinors and quaternions.
yes. every thing is matter. matter can be anything, as long as its something The three states of matter are: solid, liquid, and gas. As long as it fits into one of thsoe three categories, it is matter.
Plasma & mass
living and non- living
are name two categories used to classfly properties matter?
Classified and unclassified
Matter is classified into mixtures as to whether it is chemically bonded or just physically. A mixture is physically bonded and can be separated by physical means. Then, we have two categories. There is the homogeneous mixture and the heterogeneous mixture.
Matter is classified into four categories 1 Solid 2 Liquid 3 Gas 4 Ionic (plasma)
The properties of matter are divided into two sub categories. Those categories are the physical properties of matter and the chemical properties of matter.
They can generally be classified as either a warning or information.
