Aare yar ....Suno...Kal mera Science-1 ka paper hai...
...IMP...do na
Answers
Answer:
Study refraction of light and lenses very thoroughly and don't put carbon compounds in option study the IUPAC names. Do all the give scientific reasons. And just stay calm, u will do it. And don't forget 2 study the objectives.
Yes mate, tomorrow is Science - 1 exam of SSC Maharashtra Board. The paper pattern has been changed this year. It's actually beneficial for the students. There are many options for students to solve as well as get out of marks. Let's go to the IMP questions of tomorrow's paper!
Chapter 1 => Kepler's Laws, Newton's law of Gravitation, All solved examples, any one problem from exercise, Mass and weight difference, escape velocity.
Chapter 2 => Dobereiner triads with examples, Newlands law of octaves with examples also limitations, Merits of Mendeleev's periodic table ***, Demerits of Mendeleev's periodic table **, Modern Periodic Law **, Any one give reason from exercise *****(Valency of elements belonging to the same group is same).
Chapter 3=> Types of reaction, Oxidation and reduction in terms of electron exchange, Redox Reaction with example **, Factors affecting rate of chemical reaction *, Corrosion and rust, Rancidity ***
Chapter 4=> Bulb diagram *, Fleming rules with diagram, Solved example ***, electric motor **, electric generator ***
Chapter 5=> Regelation, Anomalous behaviour of water *, Draw diagram of Hope's apparatus ***, Give reason, temperature vs time graph from exercise ***, solved example **
Chapter 6=> Refraction of light with diagram, Mirage, twinkling of stars and twinkling of planets (give reason), prism diagram (label), internal and partial reflection ***with diagram
Chapter 7=> Lenses and their types (identity), Position of object, image and their nature (from the table given in the textbook on page no. 83)***, power of lens, solved example, compound microscope **, persistence of vision (chart) ***
Chapter 8=> aqua regia *, hydraulic separation method with diagram, electrolytic reduction of alumina *****,
Roasting and calculation, corrosion (give reason),electroplating *
Chapter 9=> alkane, alkene and alkyne examples,
IUPAC nomenclature short note *, difference between ionic compounds and covalent compounds **, Oxidation reaction *, figure 9.24*** based questions for 3-5 marks,,
Chapter 10=> All astronauts and their missions with special features table **,Q 4 from exercise, figure 10.3 with explanation, figure 10.4**** to complete the boxes, short note also importance of SWAYAM, solved example, figure 10.5 label *, importance of space missions along with SLV and space shuttles, India and space technology **
Hope it helps!
