boiling point and its effects on matters

The boiling point of liquid is raised by increasing the pressure and reduced by lowering the pressure. It can be demonstrated by the apparatus shown in figure...

When we heat a solid, we add energy to the system increasing the vibration of the particles. Eventually these particles break free from their binding forces and melt. The normal melting point of a crystal is the temperature at which it melts under one atmospheric pressure. Increase in pre..

When salt is added to boiling water the temperature of boiling water is raised above 100 o C. This is because the salt absorbs heat energy from the water for dissolving in it and its average kinetic energy decreases. When gases dissolve in water it lowers the boiling ..

When a liquid is heated, the molecules gain more kinetic energy and the temperature starts rising. After it has reached a specific point though heat is being supplied, the temperature becomes steady. At this temperature the energy supplied gets utilized in breaking the inter-molecular fo..

>Filtration is a more effective method of separating an insoluble solid from a liquid. A soluble solid can be obtained back from a liquid in which it dissolves by the process of evaporation. Distillation is employed to separate and re-obtain both the solute and the solvent from a solution..

The boiling points of alkyl chlorides, bromides and iodides follow the order RI > RBr > RCl where R is an alkyl group. With the increase in the size of halogen, the magnitude of Van der Waals forces increases and, consequently, the boiling points incre..

Pure sulphuric acid on boiling decomposes to give water and sulphur trioxide. During boiling more sulphur trioxide is lost than water. As a result, the concentration becomes 98.33%. The acid of this concentration forms a constant boiling mixture with the remaining sma..

Sulphur boils at 444.6 o C and gives off light yellowish orange vapo..

Although boiling and evaporation are similar processes, yet they differ in few aspects. The main points of difference between evaporation and boiling are given below:..

Melting Points and Boiling Points - The melting and boiling points of group 14 elements are much higher as compared to those of group 13 elements. Explanation: It is because the atoms of group 14 can form four covalent bonds with each other and, the..
