2 SECTION-A Why do some atoms react with other atoms to form compounds where as some do not? Define molecule. What was the modifications introduced by Carl Woese, in the classification proposed by Whittaker? 4 0. cm 7.80 g/cc Radius of an iron sphere is 0. cm. If density of iron is 7.80 g/cc, calculate its mass. 6 A boy stands at one end of a corridor, both the doors of which are closed. When he claps the echo of the clap continues for a few seconds with decreasing loudness. Why? State the major drawback in Rutherford s model of an atom. Mention two features of Bohr s model which helped compensate this drawback. Write three rules for writing the chemical formulae. Cl. u, N 4 u, H u, S u, O 6 u) Calculate the molecular mass of the following : Chlorine gas Ammonia gas Sulphur trioxide gas (Given atomic mass of Cl. u, N 4 u, H u, S u, O 6 u) Answer the following questions in brief with reason : Do acute and chronic diseases have different effect on our health? Why any disease that causes poor functioning of some parts of the body will affect our Page of 8
3 0 general health as well? Which disease causes more effects on general health - acute or chronic? (i) (ii) (iii) Name two plants each of the following types : (i) Vascular cryptogams (ii) Naked seeded plants (iii) Flowering plants. What precautions can you take in your school to reduce the incidence of infectious diseases? 40g cm g/cm The volume of 40 g of a solid is cm. If the density of water is g/cm, will the solid float or sink in water? State reason. Why is it easier to lift a heavy stone under water? vibrations are produced in a slinky in 0 sec when a jerk is given to it. Find its time period and frequency. How can a longitudinal wave be produced in that slinky? 4 0. cm 7.80 g/cc 0.8 cm.7 g/cc Radius of an iron sphere is 0. cm. If density of iron is 7.80 g/cc. Calculate its mass. Edge of a aluminium cube is 0.8 cm. If density of aluminium is.70 g/cc., calculate its mass. () SI 6 () 0 0 ms - 0 ms - Define Power. Write its SI unit. Compute the power required by a man to move a 0 kg mass to change the speed from 0 m/s to 0 m/s in sec. Hiten received a heavy electricity bill. His friend suggested him some ways to cut down on Page of 8
4 7 the high electricity units consumption. Hiten followed those suggestions and was able to cut down on the expenditure. Suggest any two ways which help in saving electricity. What can you learn from the behaviour of his friend? 4 X 7 (i) X (ii) (iii) X X 79 Br (49.7%) 8 Br (0.%) 8 You are given an element 4 X 7. Find out (i) Number of protons, electrons and neutrons in X. (ii) Valency of X. (iii) Electronic Configuration of X. If bromine atom is available in the form of, 79 8 Br (49.7%) and Br (0.%). Calculate the average atomic mass of bromine atom. List four conventions to be followed while writing the scientific names of organisms. Who introduced the system of Binomial nomenclature? 9 0 (i) (iii) (ii) (iv)?? Name any one disease caused by each of the following - (i) Protozoa (ii) Virus (iii) Bacteria (iv) Fungi How is malaria disease transmitted? What are the common preventive measures taken against communicable diseases? Hz Represent on a graph : Two sound waves having same amplitude but different frequencies. Two sound waves having same frequency but different amplitudes. What is meant by the statement that frequency of a tuning fork is Hz. SI Page 4 of 8
5 0 kg 0. m g = 0 m/s 0 kg 0. m/s Name two forms of mechanical energy. Define the SI unit of energy. A man of mass 0 kg jumps from a height of 0. m. If g = 0 m/s, what will be his energy at the highest point? Calculate the energy of a body of mass 0 kg moving with velocity of 0. m/s. /SECTION B (OTBA) (* Please ensure that open text of the given theme is supplied with this question paper.) पर य वरण एव स वयस र Theme: Health & Environment Consuming fish with high Hg level can be a problem. How? Of human excreta, faeces are the most dangerous to health. Comment. 4 What were the findings of PPCB-PGIMER Report? 6 PPCB-PGIMER / SECTION - C In the experiment to verify the laws of reflection of sound, the most suitable screen placed between the two tubes is. Wooden Screen Glass Screen Plastic Screen Iron Screen To compare the pressure exerted by a student on a table, it will be observed that pressure will be maximum when the student will : sit on the table stand on the table sleep on the table equal in all the three cases 7 Page of 8
6 (A) (B) (C) (D) (E) (F) (G) B, G D D, G F C, G E A, G F 8 Milly, Krishna, Vinayak and Vasundhra were asked to select the apparatus required to determine the speed of the pulse propagated through a stretched slinky, which is as given below : (A) thin silk string (B) thick cotton string (C) thin cotton thread (D) a stop clock (E) a table clock (F) thick silk string (G) a metre scale The apparatus selected by them is : Milly : B, G and D Krishan : D, G and F Vinayak : C, G and E Vasundhara : A, G and F Who has selected correct apparatus? Which of the following groups is called as amphibian of plant kingdom? Algae Bryophytes Gymnosperms Angiosperms 9 X g Y g Z g X Z Y X Y Z X Y Z Y Z X If X g of Magnesium combines with Y g of Oxygen and forms Z g of Magnesium oxide, then to verify the law of conservation of mass, the correct equation is : X Z Y X Y Z X Y Z Y Z X 0 Page 6 of 8
7 While verifying the law of conservation of mass a student carried out the reaction between sodium chloride and silver nitrate in a conical flask. Which of the following will appear as a precipitate? Silver Chloride Sodium Chloride Sodium Nitrate Barium Chloride A student identified a specimen as bamboo. The basis on which he has identified is : tap roots and parallel venation in its leaf. fibrous roots and reticulate venation in its leaf. tap roots and reticulate venation in its leaf. fibrous roots and parallel venation in its leaf. Which of the following is not a feature of dicotyledonous plants : pentamerous flowers leaves with reticulate venation fibrous root system two cotyledons The stage in the life cycle of a mosquito which appears like a worm is : Larva Pupa Adult Egg 4 0 Page 7 of 8
8 To determine the density of a solid of mass 0 gm the solid was fully immersed into water. The level of water in the measuring cylinder before and after immersing of solid is shown in the diagrams. Find the density of solid. 6 In an experiment to establish the relation between the loss of weight of solid when fully immersed in a liquid to the weight of water displaced by it, is there any change in results, if we take the vessels of different shapes or we change the level of water in vessels? In an experiment to determine the loss of weight of an object when immersed in a liquid. State the factors on which the force acting on an object depends? -o0o0o0o- Page 8 of 8
