Q1:A. Answer the following in one sentenceu. 1. What is done to get rid the water of bad smells? 2. What are summer crops? 3 what are preservatiyes? c 4 write the full form of cnG and LPG 7. 5 which are the three states of water?
Answers
i-Chlorine is the most widely used oxidant to remove odor from water, but at best deemed mildly effective.
ii-Crops grown in summer are Paddy, Corn, etc.
iii-A preservative is a substance or a chemical that is added to products such as food products, beverages, pharmaceutical drugs, paints, biological samples, cosmetics, wood, and many other products to prevent decomposition by microbial growth or by undesirable chemical changes.
iv-LPG and CNG stands for Liquefied Petroleum Gas and Compressed Natural Gas, respectively
v-Water can be found in three different states: liquid, solid and gas.
The water we drink is liquid water. So is the water in the rivers, lakes and the sea. Clouds are made up of tiny drops of liquid water.
Ice, snow and hailstones are solid water.
Water vapour is a gas.
Answer:
1.Chlorine is the most widely used oxidant to remove odor from water, but at best deemed mildly effective. Oxygen and potassium permanganate are also only mildly effective water treatment solutions. Oxidizers such as ozone and chlorine dioxide are by far the most efficient in eliminating odor from water.
2.Crops grown in summer are Paddy, Corn, etc. Other examples of Summer crops are Pumpkin, Cucumber, Bitter Rice, Corn, Cucumber, Melon, Pepper, Tomato, and some coarse Cereals sown during March and are generally harvested by June end
3.preservative is a substance or a chemical that is added to products such as food products, beverages, pharmaceutical drugs, paints, biological samples, cosmetics, wood, and many other products to prevent decomposition by microbial growth or by undesirable chemical changes. In general, preservation is implemented in two modes, chemical and physical. Chemical preservation entails adding chemical compounds to the product. Physical preservation entails processes such as refrigeration or drying.[1] Preservative food additives reduce the risk of foodborne infections, decrease microbial spoilage, and preserve fresh attributes and nutritional quality. Some physical techniques for food preservation include dehydration, UV-C radiation, freeze-drying, and refrigeration. Chemical preservation and physical preservation techniques are sometimes combined.
4.LPG stands for Liquified Petrolium Gas. CNG stands for Compressed Natural Gas.
5.Water can be found in three different states: liquid, solid and gas.
The water we drink is liquid water. So is the water in the rivers, lakes and the sea. Clouds are made up of tiny drops of liquid water.
Ice, snow and hailstones are solid water.
