It has no harmful minerals or their level is too low to affect human health. Question 8. It is called global warming. What do you mean by acid rain? How does it affect both living and non-living things? Answer: Due to fossil fuel and industrial combustions that mostly emits nitrogen oxides NOx and sulphur dioxide SO2 into the atmosphere. Water vapour present in atmosphere reacts with these gases to form nitric acid and sulphuric acid. Normal rain water is slightly acidic with a pH range of 5. When the pH level of rain water falls below this range due to combining with these acids in atmosphere, it becomes acid rain.

Acid rain has significant effects on the world environment and public health. Effect on aquatic environment: Acid rain lowers pH level below 5, most fish eggs cannot hatch. Lowering in pH can also kill adult fish. Effect on forests: It makes trees vulnerable to disease, extreme weather, and insects by destroying their leaves, damaging the bark and arresting their growth. Effect on soil: Acid rain highly impacts soil microbes and biological activity as well as soil chemical compositions. Thus affecting crop production. Effect on architecture and buildings: Acid rain on buildings, especially those constructed with limestone, react with the minerals and corrode them away. This leaves the building weak and susceptible to decay. Irreplaceable damage can be caused to the old heritage buildings. Effect on public health: When in atmosphere, sulphur dioxide and nitrogen oxide gases, degrades visibility and can cause accidents, leading to injuries and deaths.

Name various techniques used for purification of water. Answer: Water which looks clean may still have disease-carrying microorganisms and dissolved impurities. So, it is essential to purify water before drinking. Municipal bodies uses various physical and chemical processes before supplying water into households. Boiling: It is a very common practice use for obtaining safe drinking water. Boiling kills the germs present in the water. Filtration: This is a physical method of removing impurities and in some cases germs also. A popular household filter is a candle type filter. Chlorination is a commonly used chemical method for purifying water. It is done by adding chlorine tablets or bleaching powder to the water. Now-a-days filter with reverse osmosis RO which causes desalination of water along with activated charcoal to filter impurities and ultraviolet lamp to kill microorganisms are also used for purification of water.

Page No Why is Mercury very hot during the day and very cold at night? Answer: Being very close to the Sun, Mercury turns extremely hot during the day with temperature rising above oC. However, Mercury's gravitational force is not strong enough to sustain the hot atmosphere. Due to the absence of this atmosphere, the heat is quickly lost at night thereby decreasing its temperature to around oC. Page No What is the most distinctive feature of Saturn? Answer: The most distinctive feature of Saturn is that it is surrounded by three wide rings of ice and dust. Page No What is the difference between meteors and meteorites? Answer: Meteors Meteorites They are small objects made up of stones present in space. As they enter the Earth's atmosphere at a high speed, they are heated up due to friction with the atmosphere and burn to ashes before reaching the surface. If a meteor is extremely large, it does not burn out completely before reaching the Earth's surface. Such meteors are called meteorites.

Answer Key 1. D The number in a subscript after each letter in a chemical formula indicates the number of atoms of that element in a single molecule. A An ion is an atom with an unequal number of protons and electrons, giving it a positive or a negative charge. Normally, an atom has an equal number of positively-charged protons as negatively-charged electrons, giving the atom an overall neutral charge. In an ion, however, some electrons have either been gained or lost, which throws off the balance and gives the ion a charge. If there are more protons than electrons, the ion will have a positive charge and be called a cation. If there are more electrons than protons, the ion will have a negative charge and be called an anion. The only choice less than 12 is D Condensation involves a slowing-down of molecules. Condensation is the process of a gas turning into a liquid.

Gas molecules move more quickly than liquid molecules, so the phase change results in slower movement. B Freezing is the process of a liquid turning into a solid. Since a solid has stronger bonds than a liquid, bonds are being formed rather than broken in this process. An exothermic reaction creates molecular bonds. A At the highest point of the roller coaster, the car would briefly stop. When not in motion, it would have total potential energy and not kinetic energy. As the car then began its descent, that potential energy would be converted to kinetic energy. On the next, lower hill, the car would again have some potential energy but inertia would keep it moving, so it would still maintain kinetic energy. B The question states that acceleration and force are directly proportional. If two things are directly proportional, they move in the same direction. So if one increases, the other also increases, and if one decreases, the other also decreases. In this case, the force decreases, so acceleration will also decrease.

Introduction to Work and the Economy Ever since the first people traded one item for another, there has been some form of economy in the world. It is how people optimize what they have to meet their wants and needs. Goods are the physical objects we find, grow, or make in order to meet our needs and the needs of others. Goods can meet essential needs, such as a place to live, clothing, and food, or they can be luxuries — those things we do not need to live but want anyway.
