VALUE POINTS 
 
PHYSICS
 
1. Relative density of a substance is defined as the ratio of its density to that of water.
 
2. Mass – Quantity of matter in it. It is a scalar quantity. SI unit of mass is kilogram. It is always constant.
Weight – The force with which it is attracted towards the centre of earth. It is a vector quantity. SI unit of weight is Newton. It varies from place to place. (any 2 differences)
 
3. Density of plastic is less than that of water. So the buoyant force acting on the block is more than its weight.
 
4. h =ut+1/2 gt2
h =0x2 +1/2 x(9.8) x4
h = 19.6 m
1/2+1/2 +1
 
CHEMISTRY
 
5. By crystallization
 
6. Chromatography: It is based on the difference in solubilities of different solutes in the same solvent. Simple Distillation: It is based on the sufficient difference in boiling points(greater than 25K) of two miscible liquids of the mixture
 
7. (a)Some elements show the properties of both metals and nonmetals. boron/silicon
 
(b)sodium & mercury are metals
 
8. (a)physical change (b) chemical change (c)chemical change (d) physical change
 
BIOLOGY
 
9. 1. Number of cells
 
2. Presence or absence of well-defined nucleus or any other two characters.
 
10. Organisms that are similar enough to breed and perpetuate.
 
11. Fungi- Multicellular, Eukaryotic. Monera-Unicellular, Prokaryotic.
