S1.Ans. (b)

Sol. Baking soda is sodium bicarbonate with chemical formula NaHCO3. It is primarily used in baking industries as a leavening agent.

S2.Ans. (b)

Sol. LPG is a mixture of C4H10 (Butane), C3H8 (propane) and C2H6 (ethane). Main constituent is butane (C4H10).

S3.Ans. (b)

Sol. Liquid hydrogen and liquid oxygen are used as excellent fuel for rockets. H2(l) has low mass and high enthalpy of combustion whereas oxygen is a strong supporter of combustion.

S4.Ans. (a)

Sol. Bullet-proof windows are constructed using several layers of polycarbonate and/or laminated glass.

S5.Ans. (c)

Sol. One of the key organelles involved in digestion and waste removal is lysosome. Lysosomes are organelles that contain digestive enzymes.

S6.Ans. (a)

Sol. A detergent is a cleansing agent. Both detergents and soap can clean, but they are different chemically. A soap is the metal salt of long-chain fatty acid. The metal may be an alkali metal such as sodium (Na) or potassium (K).

S7.Ans. (a)

Sol. A gas, when kept at a constant temperature, would obey the gas laws exactly. The gas laws are Charle’s law, Boyle’s law and Gay-Lussac’s law.

S8.Ans. (b)

Sol. When the osmotic pressure outside the red blood cells is the same as the pressure inside the cells, the solution is isotonic with respect to the cytoplasm. This is the usual condition of red blood cells in plasma. Hence the cells do not shrink.

S9.Ans. (d)

Sol. Xylem tissue is the specialized conducting system of the plants. It is the main conducting system for water and some mineral nutrients from roots to the shoot.

S10.Ans. (a)

Sol. The value of g decreases with height and depth from the earth’s surface. The intensity of the Gravitational field of the Earth is maximum at the poles and it is minimum at the equator. The value of g decreases due to the rotation of the Earth. Poles being a little closer to the centre of gravity, intensity of gravity is the maximum.
