Specific heat of water = 4.184 J/g.oC Heat released by dissolution = Heat absorbed by solution = mass of solution (NaOH + water) x specific heat of water x temperature change = (2.0 + 49.0) x 4.184 x 10.5 = 2240.532 J Moles of NaOH = mass of NaOH/molar mass of NaOH = 2.0/40.00 = 0.05 mol Heat of dissolution H = -heat released by dissolution/moles of NaOH = -2240.532/0.05 = -4.48 x 104 J/mol (H is negative as the dissolution is exothermic) Solution Specific heat of water = 4.184 J/g.oC Heat released by dissolution = Heat absorbed by solution = mass of solution (NaOH + water) x specific heat of water x temperature change = (2.0 + 49.0) x 4.184 x 10.5 = 2240.532 J Moles of NaOH = mass of NaOH/molar mass of NaOH = 2.0/40.00 = 0.05 mol Heat of dissolution H = -heat released by dissolution/moles of NaOH = -2240.532/0.05 = -4.48 x 104 J/mol (H is negative as the dissolution is exothermic).

These are two of the three major perspectives on sociology. Each of them understands society and social phenomena in a very different way. Functionalism looks at the large structures in our society while symbolic interactionism looks at the way in which individuals act within the society. According to the functionalist perspective, everything in a society has a role that is necessary for the functioning of the society. This means that even poverty and economic inequality, for example, play an important role in keeping our society stable. Symbolic interactionism does not ask about such \"big picture\" questions as why poverty persists. Instead, it looks at how individuals act. It says that people attach meanings to various things that they see as symbols in our society. They then act in ways that accord with the meaning that they attribute to those symbols. According to the symbolic interactionist perspective, people attach meanings to symbols, and then they act according to their subjective interpretation of these symbols. Verbal conversations, in which spoken words serve as the predominant symbols, make this subjective interpretation especially evident. The words have a certain meaning for the “sender,” and, during effective communication, they hopefully have the same meaning for the “receiver. Consider applying symbolic interactionism one of the spouses may see their circular wedding rings as symbolizing “never ending love,” while the other may see them as a mere financial expense. symbolic interactionists may miss the larger issues of society by focusing too closely on the “trees” (for example, the size of the diamond in the wedding ring) rather than the “forest” (for example, the quality of the marriage). The perspective also receives criticism for slighting the influence of social forces and institutions on individual interactions.the conflict perspective focuses on the negative, conflicted, and everchanging nature of society. Unlike functionalists who defend the status quo, avoid social change, and believe people cooperate to effect social order, conflict theorists challenge the status quo, encourage social change (even when this means social revolution), and believe rich and powerful people force social order on the poor and the weak. Conflict theorists, for example, may interpret an “elite” board of regents raising tuition to pay for esoteric new programs that raise the prestige of a local college as selfserving rather than as beneficial for students. According to the functionalist perspective, also called functionalism, each aspect of society is interdependent and contributes to society\'s functioning as a whole. The government, or state, provides education for the children of the family, which in turn pays taxes on which the state depends to keep itself running. That is, the family is dependent upon the school to help children grow up to have good jobs so that they can raise and support their own families. In the process, the childr.

The emotional and psychological effects the HIV/AIDS epidemic on the diagnosed individual :- HIV effected indiviual get emotionally and psychologicaly very depressed. He felt isolated himself from his social groups. They are more prone to infections. The friends and family members:- Earlier, the friends and family members accused that person, they blame to patient about what he did, but now the thinking of peoples also getting changed. Peoples are getting more aware about the infection and causes of infection. Educated peoples don\'t blame to the patient, they support them, and also tries to improve thier emotional level. The community as a whole:- The community as a whole blame the infected person. They make him isolate, and extrude out of the society. This phenomenon is very common, because of lack of awareness about the HIV infection. Some people have made thier psychology that, HIV infected only by mean of sex. But the fact is HIV can occur by number of means like use of infected syringe and wrong blood transfusion. An emotionally, community symphathise the infected person but they don\'t want to accept him, make a sepration towards him.

Since the gene responsible for the color of pea and shape of seed of pea are not on different chromosome, yet Mendel acheives the sucess on explaining the segregation of the two different gene whether they are present on same chromosome or they present on different chromosome. When Mendel crossed the yellow coloured round seed plant with the green coloured wrinkled plant the result is only yellow coloured round seed plant. Although when Mendel crossed the yellow coloured wrinkled seed plant with the green coloured round seed plant, the result was same i.e. yellow coloured round seed plant. It means that the gene responsible for the yellow colour and round shape does not blend with each other i.e. does not mix with each other. They segregate during fertilization if still they present on same chromosome or on different chromosome.
