Physical change is temporary change, but chemical change is permanent change.

Meghna Thapar 5 years, 6 months ago

Those changes in which no new substances are formed are called physical changes. But the properties like state, size, shape and colour changes. If we cut the piece of paper in four parts and again we cut the paper into another four pieces, we cannot join the pieces but the properties are changed. Those changes in which new substances are formed are called chemical changes. The properties of new substances formed in a chemical changes are entirely different from those of the original substances. Chemical changes are also called as chemical reactions. The chemical changes are permanent changes which can usually not be reversed to form the original substance. Large amount of energy is absorbed or lost during the process.

Cataract is a condition in which the crystalline lens of people at old age becomes milky and cloudy resulting in blurred vision. Most cataracts develop when aging or injury changes the tissue that makes up your eye's lens. Some inherited genetic disorders that cause other health problems can increase your risk of cataracts. Cataracts can also be caused by other eye conditions, past eye surgery or medical conditions such as diabetes.

Germany: Nationalist feelings were widespread among middle class Germans, who in 1848 tried to unite different regions of the German confederation. This movement was suppressed by combined forces of monarchy and military, supported by large landowners (Junkers) of Prussia. Then Prussia's chief minister, Otto von Bismarck, took the leadership of the movement for national unification. Three wars over seven years with Austria, Denmark and France ended in Prussian victory and completed the process of unification. In January 1871, Prussian king William I was proclaimed German Emperor in a ceremony held at Versailles.
 Italy: Prime Minister Cavour and King Victor Emmanuel formed an alliance with France to overthrow Austria. This alliance united northern Italy. At the same time in the South, Garibaldi used guerilla warfare to unite southern Italy. People in the south voted to join the people in the north, thus uniting Italy.

Self Help Group (SHG) is a group of about 15-20 members who pool their savings together. Following are the advantages of SHG:

  1. Members can take loans from the group’s savings themselves on a decided rate of interest. The rate of interest is much lower than the interest that is charged by the informal sources.

    After two years of regular savings, the SHG can also take a loan from the bank. Loan is given on the name of the group and creates tremendous opportunities for self-employment of the members.

  2. Due to SHG, the poor members are able to avail loan even in the absence of collateral.

  3. Many women as the members of SHGs have become economically independent. This has led to women empowerment at the rural levels.

A displacement reaction is the one wherein the atom or a set of atoms is displaced by another atom in a molecule. For instance, when Iron is added to a copper sulphate solution, it displaces the copper metal.

A + B-C → A-C + B

The above equation exists when A is more reactive than B.

A and B have to be either:

  • Halogens where C indicates a cation.
  • Different metals wherein C indicates an anion.
