How is Newton\'s 3rd law of motion similar to law of conservation of momentum? |
|
Answer» It\'s completely related How means the third law states about the force and momentum and it also tells us that there is an equal & opposite force acting upon it & in that conservation law you find that when body B falls on body A ,it moves as much as body B does? Netwon third law say that for every action there is a equal and opposite reaction and in conservation of momentum body A apply force on body B and also body B apply equal and opposite force on body A |

Define centrification ? |
|
Answer» Centrifugation is a process by which we can seperate cream from milk etc.The principle is that when we countineously stir a solution the lighter particles come in center in case of cream and heavier particles get on side in case of milk.hope it will help you.??? Centrifugation is the process of seperating cream from milk through centrifuge device. It is similar to the churning curd Doctors use it to separate all the components from blood.? Centrifugation???? It is the process of separating cream from milk by stirring with the help of centrifuge by using centrifugal force in which the heavier particles settle down and water floats. Centrifugation is a process of separating cream from milk by stirring continusly the heavier particles (cream) settle down and water floats (milk) . This can also be done by centrifuge stirrer in chemistry lab Centrifugation in the process to separate the particles which are very small and can easily pass through filter paper. . ???? |

During burning both physical and chemical changes take place. Can you distinguish these |
| Answer» When a candle burns, both physical and chemical changes occur.Physical Changes in Burning Candle: On heating, candle wax melts and form liquid wax. It is a physical change. Since it again turns into solid wax on cooling. This is a reversible change.Chemical Changes in Burning Candle:\xa0When you light the candle, the wax present near the wick will melt. Wick absorbs the liquid wax. The liquid wax vaporizes due the heat produced by the flame. This wax vapor near to flame\xa0burns and gives new substances like Carbon Dioxide, Carbon soot, water vapours, heat and light. This is an irreversible change. | |

Write the steps and processes involed in nitrogen cycle |
| Answer» The various steps of nitrogen cycle are as follows :(i) Nitrogen fixation: It is the conversion of atmospheric nitrogen into water-soluble compounds like nitrates and nitrites either by the free-living bacteria or Rhizobium that are found in the root nodules of legumes. Atmospheric nitrogen also gets converted into nitrates and nitrites naturally by lightning.(ii) Ammonification: Death and decay of plant bodies release ammonia into the atmosphere. Animals also give out ammonia along with urea and uric acid as excretory products. These nitrogenous compounds are converted to ammonia by putrefying bacteria and the process is known as ammonification.(iii) Nitrification: Ammonia is then onverted first into nitrites and then into nitrates by the nitrifying bacteria, the process being called as nitrification. Plants generally take up nitrates and nitrites and convert them into amino acids.(iv) Denitrification: When the animal or the plant dies, denitrifving bacteria in the soil convert the various compounds of nitrogen back into nitrates and nitrites. The nitrates and nitrites are çonverted into elemental nitrogen by Pseudomonas. This process is called denitrification. | |

Difference between simple distillation and fractional distillation |
| Answer» 1. Simple distillation is the method used to separate substances in mixtures with significantly different boiling points, while fractional distillation is used for mixtures containing chemicals with boiling points close to each other.2. Simple distillation will only have one distillation (vaporization-condensation) cycle in the whole process, while the fractional cycle will have at least two cycles.3. Fractional distillation will use additional equipment called the ‘fractionating column’, while the simple distillation will not need that equipment.4. Simple distillation is often used to separate the liquid substance from the solid substance. Doing such separation with fractional distillation is not sensible. | |
