Science Class 10 Question Paper

SECTION A
1. How many pairs of chromosomes are present in human beings ? 
 
2. Define pole of a spherical mirror. 
 
3. Answer question numbers 3(a) - 3(d) on the basis of your understanding of the following paragraph and the related studied concepts :
 
Matter around us is found in the form of elements, compounds and mixtures. The elements contain atoms of only one type. Around the year 1800, only 30 elements showing different properties were known.
 
Scientists of that age discovered a pattern in their properties and based on that pattern, several attempts were made to classify elements. The earliest attempt was to classify the elements as metals and non-metals.
 
The latest is the ‘Modern Periodic Table’. This table consists of 7 periods and 18 groups. Each element of a group in the periodic table has the identical outer shell electronic configuration. In other words, the groups in the periodic table signify an identical outer shell electronic configuration. As we go down the group in the periodic table, the number of shells increases.
 
3(a) Write the need to classify elements. 
 
3(b) How many groups are there in the ‘Modern Periodic Table’ ? 
 
3(c) Which one of the following statements is not correct about the ‘Modern Periodic Table’ ? 
 
(A) It is based on atomic masses.
 
(B) The position of isotopes is not disputed.
 
(C) The position of isotopes is easily assigned.
 
(D) It separates metals from non-metals.
 
3(d) The cause of periodicity of properties of elements is 
 
(A) Increasing atomic radius
 
(B) Increasing atomic mass
 
(C) Increasing nuclear charge
 
(D) The recurrence of similar outer electronic configuration
 
4. Answer question numbers 4(a) - 4(d) on the basis of your understanding of the following paragraph and the related studied concepts :
 
There are different forms of energy and one form of energy can be converted into another. When we light a wax candle, the process is highly exothermic and on burning, the chemical energy of the wax gets converted into heat and light. A good source of energy is to be selected for the choice of work to be done. In ancient times, wood was the most
common source of heat energy. We, in our daily lives, use various energy sources for doing the work. Nowadays we use diesel and electricity to run trains. We also use fossil fuels in vehicles which has some serious disadvantages, mainly air pollution. The recent example of air pollution was ‘Smog’ in the National Capital Region of Delhi. This pollution was a
result of burning ‘Parali’ in northern states of the country, which affected the eyes and also caused serious respiratory problems.
