Give reason why copper is used to make hot water tanks and not steel ( an alloy of iron). |
|
Answer» Thank you all friend Cu, Ag, Au and Pb this all are not react with any water. Copper does not react with hot water , cold water and steam water and Cu, Ag, Au and Pb Copper does not react with cold water, hot water or steam however iron reacts with steam. If water tanks are made of steel which is an iron alloy than iron would react with steam formed from hot water.3Fe + 4H2\u200bO →Fe3\u200bO4\u200b + 4H2\u200bThat is why copper is used to make hot water tanks and not steel. Because iron will rust. |

Why does clear sky appears blue? |
|
Answer» Sunlight reaches Earth\'s atmosphere and is scattered in all directions by all the gases and particles in the air. Blue light is scattered more than the other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time. The sunlight that reaches the earth’s atmosphere is scattered in all directions by the gases and dust particles present in the atmosphere. The blue colour is scattered more and hence the sky appears blue. The reason for more scattering of blue colour is that the wavelength of the blue light is shorter than the other light. So blue light is scattered in all directions by the tiny molecules of air in Earth’s atmosphere. This the reason for the blue appearance of the sky. |

Explain the mechanism of impulse transmission by a neuron. |
|
Answer» Impulse is actually an electrical signals transmitted by neuron to brain a d further brain decides it and sent the requires and respective works that has been enacted by body two Britons are connected through a medium called synapse , the synaptic Bob\'s of two neurons consists of chemicals from which they signals for further processing and sensory neuron senses the signals and sent it to brain and further motar neuron sent back the drew procssing~~?? Thanks for your answer?Good evening shiva✌?It\'s ok harsh if you don\'t know the answer ?? The transmission of nerve impulse from one neuron to another one takes place through the synapse, a minute gap between the nerve ending of one neuron and the dendrites of another neuron. The signal is first detected by the dendrites and then transmitted to the cell body, from where it reachs the nerve ending via the axon. From the nerve ending through the synapse it travels to another neuron. You get up good morning priya Idk |

Different between heredity and evolution |
| Answer» Heredity: The passing of traits from the parents to offspring is called heredity. This is heredity which is responsible for many commonly observable facts; like siblings looking similar in overall appearance.Evolution: The change in inherited traits in biological population over subsequent generations is called evolution. Scientists have proven that life evolved in the form of simple unicellular organisms on this earth; and all the organisms which are present today have evolved from a common ancestor. The idea of evolution is based on the premise of a common ancestry. | |
| 180. |
Explain this term lamarckism |
| Answer» Lamarckism, a theory of evolution based on the principle that physical changes in organisms during their lifetime—such as greater development of an organ or a part through increased use—could be transmitted to their offspring. The classic example used to explain the concept of use and disuse is the elongated neck of the giraffe. According to Lamarck\'s theory, a given giraffe could, over a lifetime of straining to reach high branches, develop an elongated neck. | |

Give reason : Most metals conduct electricity well. |
|
Answer» As metals are good conductors of heat thus when electrons passes through the metals then the kinetic energy becomes stronger and thus it helps the electrons to move more fastly in the metals and thus metals are known as good conductor of electricity.. Most metal conduct electricity well because electron inside the metal are relatively free to move . So when electricity is pass through metals ,electron carry electricity and spread it all over the metal Metals conduct electricity because they have electrons which are free to move. They offer little resistance to the flow of current. Silver and copper are the best conductors of electricity |

Why magnesium ribbon be cleaned before burning? |
|
Answer» In order to make the oxidation process more easily as well as effective. ????? Nhi apni notebook se copy kiya hai? Priya aapne google se copy kiya na? The magnesium ribbon should be cleaned before burning in the air because the layer of magnesium oxide (which is formed due to the reaction of magnesium with air ) can be removed in order to get the desired chemical reaction. Also in order to remove the oxide layer, the presence of which slowdowns the oxidation process. So, by cleaning it, the burning process takes place easily. |

why compass north pole attractes earth\'s north pole? |
|
Answer» hii? The Earth is a magnet that can interact with other magnets in this way, so the north end of a compass magnet is drawn to align with the Earth\'s magnetic field. Because the Earth\'s magnetic North Pole attracts the "north" ends of other magnets, it is technically the "South Pole" of our planet\'s magnetic field. Hlo Because of its magnetic properties.?? The Earth is a magnet that can interact with other magnets in this way, so the north end of a compass magnet is drawn to align with the Earth\'s magnetic field.

How is POP chemically different from gypsum? How can they be interconverted?Write two uses of POP. |
|
Answer» It is not 380 k it is 373 k (100°C) because if it is heated above 373k so dead burnt plaster (CaSo4) is formed. Plaster of Paris is calcium sulphate hemihydrate (CaSO4. V2H2O) while gypsum is calcium sulphate dihydrate (CaSO4.2H2O).Gypsum, when heated at a temperature of about 380K, changes to Plaster of Paris.Plaster of Paris, when mixed with water, changes into hard mass called gypsum.Plaster of Paris is used in hospitals for setting fractured bones.It is used for making moulds or casts for toys pottery, ceramics etc. |
