WebDescribe what happens to the average kinetic energy of ideal gas molecules when the conditions are changed as follows: (a) The pressure of the gas is increased by reducing the volume at constant temperature. (b) The pressure of the gas is increased by increasing the temperature at constant volume. Webkinetic theory of gases, a theory based on a simplified molecular or particle description of a gas, from which many gross properties of the gas can be derived. The British scientist …

WebThe postulates of the particle theory of matter are given as: 1. All matter is made up of tiny particles known as atoms. 2. Particles of matter are constantly in motion. 3. Particles of matter attract each other. 4. Particles of matter have spaces between them. 5. As temperature increases, particles of matter move faster. 6.

In chemistry, the history of molecular theory traces the origins of the concept or idea of the existence of strong chemical bonds between two or more atoms. The modern concept of molecules can be traced back towards pre-scientific and Greek philosophers such as Leucippus and Democritus who argued that … See more The earliest views on the shapes and connectivity of atoms was that proposed by Leucippus, Democritus, and Epicurus who reasoned that the solidness of the material corresponded to the shape of the atoms involved. … See more Similar to these views, in 1803 John Dalton took the atomic weight of hydrogen, the lightest element, as unity, and determined, for example, that the … See more • History of chemistry • History of quantum mechanics • History of thermodynamics See more • Geometric Structures of Molecules - Middlebury College • Atoms and Molecules - McMaster University See more An early precursor to the idea of bonded "combinations of atoms", was the theory of "combination via chemical affinity".
