The criterion for a chemical change is the production of one or more new substances. Therefore, certain conditions should be met in order to bring about a chemical change. The necessary conditions are: 1) A minimum amount of energy needed to initiate a reacti..

Is Matter Around us Pure - Physical and Chemical Changes Matter undergoes certain changes as a result of the application of energy. Water from saltpans on the seacoast dry up, leaving behind salt; water from the sea evaporates to from water vapour, which convert into c..

Energy changes in chemical reactions can also take place in forms other than heat, such as light, electricity, mechanical energy, etc. Some common examples are: The burning of petrol or diesel in motor engines of cars, trucks, tractors or buses produces mechanical energy, whi..

There are many reactions in which energy is evolved while in others energy is absorbed. Depending upon evolution or absorption of energy, the chemical reactions can be classified into two types: Exothermic reactions and endothermic reaction..
