Q6. Arrange the following in the order of: (a) Force of attraction (b) Intermolecular space.Iron nail, Kerosene oil and Oxygen gas. Give reasons. |
|
Answer» Solid has most attraction of forces followed by liquid and then gas. This is why solid is most dense, then liquid and then gas. Gas has most intermolecular space, followed by liquid and then gas. This is because of intermolecular attraction between molecules. The more intermolecular attractions, the less is intermolecular space. Iron NAIL is solid, KEROSENE SOIL is liquid, and oxygen is a gas. So, Force of attraction Iron nail > Kerosene oil > Oxygen Intermolecular spaces Oxygen > Kerosene oil > Oxygen |

Write down a short note on pearl industry |
|
Answer» Explanation: A pearl is a hard, glistening object produced within the soft tissue (specifically the mantle) of a living shelled mollusk or another animal, such as a conulariid. Just like the shell of a mollusk, a pearl is composed of CALCIUM carbonate (mainly aragonite or a mixture of aragonite and calcite)[3] in minute CRYSTALLINE form, which has been deposited in CONCENTRIC LAYERS. The ideal pearl is perfectly round and smooth, but many other shapes, known as baroque pearl can occur. The FINEST quality of natural pearls have been highly valued as gemstones and objects of beauty for many centuries. Because of this, pearl has become a metaphor for something rare, fine, admirable and valuable. |

Why overdose of antibiotics is harmful |
|
Answer» Answer: Taking antibiotics for colds and other viral illnesses not only won't work, but it can ALSO have dangerous side effects — over time, this practice actually helps create BACTERIA that are harder to kill. Frequent and inappropriate use of antibiotics can cause bacteria or other microbes to change so antibiotics don’t work against them. This is called bacterial resistance or antibiotic resistance. TREATING these resistant bacteria requires higher doses of medicine or stronger antibiotics. Because of antibiotic overuse, certain bacteria have become resistant to EVEN the most powerful antibiotics available today. |

Synthetic fibre and its uses |
|
Answer» Answer: Synthetic fibers (British English: synthetic fibres) are fibers made by humans with CHEMICAL synthesis, as opposed to natural fibers that humans get from living organisms with little or no chemical changes. They are the result of EXTENSIVE research by scientists to IMPROVE on naturally occurring animal fibers and plant fibers. In general, synthetic fibers are created by extruding fiber-forming materials through spinnerets, forming a fibre. These fibers are called synthetic or artificial fibers.Synthetic fibres are created by a process known as polymerisation which includes combining monomers to make a long chain or polymer.The word polymer comes from a Greek prefix "POLY" which means "many" and suffix "mer" which means "single units".(Note:each single units of a polymer is called monomer).Polymerisation are of two types:linear polymerisation and Cross-linked polymerisation.

Free 100 points just tell all modes of nutrients for animals |
|
Answer» Answer: We all know that the plants can MAKE their own FOOD through the process of photosynthesis, however, animals and human beings cannot make food for themselves. They obtain food from plants and other animals that feed on plants. Thus, it is seen that human beings and animals depend on plants for their food – somewhere directly or indirectly. Green plants are autotrophic and synthesize or make their own food by the process of photosynthesis. They do this with the HELP of carbon dioxide and water in the presence of sunlight. Photosynthesis is the process by which the green plants make their own food ( like glucose ) from carbon dioxide and water by using the sunlight energy in the presence of chlorophyll. On the basis of their modes of nutrition, all the organisms are divided into two main groups – autotrophs and heterotrophs. Their corresponding modes of nutrition are known as the autotrophic and heterotrophic mode of nutrition. Those organisms that can make food themselves from simple substances like carbon dioxide and water are called autotrophs. Their mode of nutrition is referred to as autotrophic. They do this by the process of photosynthesis. All the green plants are called autotrophs. This is due to the FACT that the green plants make their own food from very simple substances like carbon dioxide and water that is present in the surroundings. They do this by the process of photosynthesis. We can also say that the green plants have an autotrophic mode of nutrition. These green plants contain a green PIGMENT called chlorophyll which further helps in making food by absorbing energy received from the sunlight. Majorly the green plants synthesize their own food – not only for themselves but also for the non-green plants, animals as well as human beings. Heterotrophs are referred to those organisms which cannot prepare their own food. They are dependent on green plants or animals for their food. Their mode of nutrition is known as the heterotrophic mode of nutrition. All the non-green plants and animals, inclusive of human beings, are called heterotrophs. The non-green plants lack chlorophyll which is necessary to carry out the process of food referred to as photosynthesis. Therefore, they depend on other organisms i.e. plants and animals in order to obtain food. The non-green plants, for example. Fungi, yeast, mushroom, bread mold, are called heterotrophs. They have a heterotrophic mode of nutrition. Therefore, all animals like dogs, cats, cow, buffalo, lion, tiger, deer as well as human beings are called heterotrophs. Their mode of nutrition called ‘ heterotrophic mode of nutrition ‘. |

The mixture made by mixing Potassium Nitrate, Sulphur & Charcoal is termed as.... |
|
Answer» Answer: Gunpowder, also known as black powder to distinguish it from modern smokeless powder, is the earliest known chemical explosive. It consists of a mixture of sulfur (S), charcoal (C), and potassium NITRATE (saltpeter, KNO3). The sulfur and charcoal act as fuels while the saltpeter is an oxidizer.[1][2] Because of its incendiary properties and the amount of heat and gas volume that it generates, gunpowder has been widely used as a propellant in firearms, artillery, rockets, and fireworks, and as a blasting powder in quarrying, mining, and road building. Gunpowder was invented in 9th-century China and spread throughout most parts of Eurasia by the end of the 13th century.[3] Originally developed by the Taoists for MEDICINAL purposes, gunpowder was first used for warfare about 1000 AD.[4] Gunpowder is classified as a low explosive because of its relatively slow decomposition rate and consequently low brisance. Low explosives deflagrate (i.e., burn) at subsonic SPEEDS, whereas high explosives DETONATE, producing a supersonic wave. Ignition of gunpowder packed behind a projectile generates enough pressure to force the shot from the muzzle at high speed, but usually not enough force to rupture the gun barrel. Gunpowder thus makes a good propellant, but is less suitable for shattering rock or fortifications with its low-yield explosive power. However, by transferring enough energy (from the BURNING gunpowder to the mass of the cannonball, and then from the cannonball to the opposing fortifications by way of the impacting ammunition) eventually a bombardier may wear down an opponent's fortified defenses.
