We have seen that the molecules in a gas in constant random motion. The spaces between them are large and the intermolecular attractions negligible. However, in a liquid the molecules are in contact with each other. The forces of attraction between the molecules are strong enough to ho…
The study of the flow of heat or any other from of energy into or out of a system as it undergoes a plysical or chemical transformation, is called Thermodynamics. In studying and evaluation the flow of energy into or out of a system, it will be useful to consider changes in certain prope…
With its a know of electronic structure of atoms and their orbitals as background, we now proceed to discuss the behaviour of atoms when their 'atomic orbital' interact to from Chemical bond Free atomic have a random motion and prosess energies. Farther the atoms are more will …
All matter in there states: gas, liquid and solid. A molecular level representation of gases, liquid and solid states is shown in figure: A gas consists of molecules separated wide apart in empty space. The molecules are free to move about throughout the container. A liquid has molecule…
