16. Which of the following statements is/are correct about compounds?

(a) It shows the properties of the constituent substances.

(b) The composition of each new substance is always fixed

(c) The constituents can be separated only by Chemical or electrochemical reactions.

Choose the correct option from the codes given below.

Correct Answer: (1) (b) and (c)
Solution:A compound is a substance composed of two or more elements, chemically combined with one another in a fixed proportion.
  • The composition of each new substance is always fixed. Hence, statement (b) is correct.
  • The new substance has totally different properties. A mixture shows the properties of the constituent substances. Hence, statement (a) is incorrect.
  • The constituents can be separated only by chemical or electrochemical reactions. Hence, statement (c) is correct.

17. Which of the following statements is/are correct about the properties of a Colloidal Solution?

(a) A colloid is a heterogeneous mixture.

(b) The solute particles settle down when colloids are left undisturbed, hence, colloids are unstable.

(c) Colloids are big enough to scatter a beam of light passing through it and make its path visible

Choose the correct option from the codes given below :

Correct Answer: (4) (a) and (c)
Solution:A colloid is a heterogeneous mixture whose particles are not as small as solution but they are so small that cannot be seen by naked eye. Hence, statement (a) is correct.
  • The colloidal particles are smaller and not heavy. They always remain in a state of zig-zag motion, called Brownian movement, which counters the force of gravity acting on colloidal particles and hence, helps in providing stability to colloidal sols by not allowing them to settle down. Hence, statement (b) is incorrect.
  • The colloidal particles with size (1nm - 1000nm) are enough to scatter a beam of light passing through them. This scattering of a beam of light by colloidal particles is called Tyndall effect. Hence, statement (c) is correct.

18. Which film won the 'Best Film on Social Issues' Award in the 68th National Film Awards under the feature films category?

Correct Answer: (4) Funeral (Marathi)
Solution:Marathi 'Funral,' (Funeral) bagged the 'Best Film on Social Issues' at the 68th National Awards.
  • Tamil feature Soorarai Pottru was named the best film of the year.
  • Legendary actress Asha Parekh got the Dadasaheb Phalke Award of 2020 for her out-standing lifetime contribution to Indian cinema.

19. 'Demographic Transition', a concept developed by Frank Notestein in 1945, described the relationship between economic development and

Correct Answer: (4) Death and Birth rate
Solution:The demographic transition theory examines the relationship between economic progress and population expansion.
  • Demographic transition is a concept coined by Warren S. Thompson (1929) and later popularized by Frank W. Notestein (1945) to describe a historical process of change that explains trends in births, deaths, and population increase in today's industrialized civilizations, particularly European societies.

20. Which among the following will not be ordinarily considered an outcome of globalization ?

Correct Answer: (4) Tariff barriers
Solution:Outsourcing is one of the important outcomes of the globalisation process. In outsourcing, a company hires regular service from external sources, mostly from other countries, which was previously provided internally or from within the country.
  • Globalisation has led to a rapid increase in foreign direct investment and foreign exchange reserves. The foreign investment, which includes foreign direct investment (FDI) and foreign institutional investment (FII).
  • The WTO agreements cover trade in goods as well as services to facilitate international trade (bilateral and multi-lateral) through removal of tariff as well as nontariff barriers and providing greater mar-ket access to all member countries. Hence, tariff barrier is notconsidered an outcome of globalization.
