Time Allowed: 3 hours
Maximum Marks: 80
General Instructions:
1. This question paper consists of 39 questions in 5 sections.
2. All questions are compulsory. However, an internal choice is provided in some questions. A
student is expected to attempt only one of these questions.
3. Section A consists of 20 objective type questions carrying 1 mark each.
4. Section B consists of 6 Very Short questions carrying 02 marks each. Answers to these
questions should in the range of 30 to 50 words.
5. Section C consists of 7 Short Answer type questions carrying 03 marks each. Answers to
these questions should in the range of 50 to 80 words.
6. Section D consists of 3 Long Answer type questions carrying 05 marks each. Answer to these
questions should be in the range of 80 to 120 words.
7. Section E consists of 3 case-based units of assessment of 04 marks each with sub-parts.
SECTION-A
1. Rutherford scattering experiment fails for very small scattering angles because:-
(a)velocity of the of a-particles is very large.
(b) gold foil is very thin.
(c) whole nuclear charge of the target atom is not screened by its electrons at all.
(d) the impact parameter between the alpha-particles source nucleus of the target is very large
as compared to the nucleus to size of the nucleus.
Or
alpha-particles are
(a)H+
, (b) He+
(c) He2+
(d) He
2. Usha Swims in a 90 m long pool, she covers 180m in one minute going either way. The
average velocity is -
a) 30m/s
b) zero
c) 180m/s
d) 90m/s
3. Heat affects the formation of solution because change in temperature cause:
(a) increases the size of water particles
(b) Changes the shape of water molecules.
(c) changes the energy of the particles.
(d) decreases the intermolecular spaces between the particles.
4. Fermentation of grapes is an example of
(a) Redox Reaction
(c) Chemical change
(d) Physical Change
