The particle theory of matter states that all matter is made up of tiny particles, specifically atoms and molecules, and that these particles have inherent characteristics. A major part of the theory is the belief that all particles in a single pure substance are the same and are different from particles of other substances.Continue Reading
The theory also maintains that there is space between all particles, that the particles are always moving, that they are attracted to one another and held together by strong forces and that the particles move faster as they gain energy or have a rise in temperature.
Since the term "matter" is used to describe anything that has substance, the particle theory of matter is essential to exploring how space is occupied in the world. It is often used to explain the properties of solids, gases and liquids. It also aids in understanding specific scientific phenomena, such as physical changes that occur with melting, sublimation, fusing, boiling, dissolving and evaporation. In addition, the theory explores physical properties like density, thickness, viscosity, luster, malleability and conductivity. It further gives credence to the supposition that all pure substances are also homogeneous, consisting of only one specific type of particle in the form of an atom, molecule or element.Learn more about Particle Physics
The modern atomic theory is a theory that all matter is composed of tiny particles called atoms. This theory is used in physics and chemistry to explain the behavior of all matter.Full Answer >
Daniel Bernoulli's kinetic theory of matter states that all things – liquids, solids or gases – are made up of atoms and molecules that are in constant motion. The theory also states that collisions between atoms and molecules are elastic.Full Answer >
A particle diagram is a visual representation of the particles of a substance, with the particles typically represented as dots. Digital particle diagrams can also show the movement of particles within a particular substance.Full Answer >
A cyclotron is a particle accelerator that uses electrical power to accelerate charged particles in a spiral path. The collision of particles produces certain radioactive isotopes for medicine, industry and scientific research.Full Answer >
