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.Know More
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
According to the kinetic molecular theory, particles in a gaseous state, whether in the form of molecules or atomic gases, are in constant, straight-line motion, occasionally bouncing off each other in perfectly elastic collisions which change their direction without slowing them down. It depends on a number of assumptions, such as the idea that the particles are very small compared to the space between them.Full Answer >
The atomic theory is that all matter is made up of tiny units or particles called atoms. This theory describes the characteristics, structure and behavior of atoms as well as the components that make up atoms. Furthermore, the theory states that all elements are made up of identical atoms.Full Answer >
The atomic theory formulated by the British chemist John Dalton proposes that atoms are indivisible particles comprising all matter; atoms of the same element share identical properties, including shape, size and mass; atoms of an element are unique and vary from the atoms of different elements; atoms are the fundamental units of a chemical reaction; atoms are conserved and can neither be created nor destroyed; and atoms combine in simple, fixed proportions to produce compound atoms, known as molecules. Dalton is commonly referred to as the father of the modern atomic theory.Full Answer >
The three main points of the kinetic theory of matter are all matter consists of molecules and atoms; these molecules and atoms are constantly in motion; and as the temperature increases, the speed of the particles, and therefore the energy of the matter, increases. Each of these three points, once further explained, reveal how and why matter can change between the three phases of solid, liquid and gas.Full Answer >
