It is usually made of materials with low melting points like copper or an alloy of tin and lead. So, whenever excess current flows through the circuit, the heat produced in the conductor would become high. This heat makes the fuse wire, connected in series with the circuit, melts off thus, disconnecting the circuit. Fuse acts like a melting wire in electric appliance . It is connected to the wire so that if short circuit takes place, fuse will melt and break the circuit to prevent appliances catching fire |

Why do silver chloride stored in dark coloured bottle |
|
Answer» Silver chloride is stored in dark coloured bottles so that not to expose to sunlight as when exposed to sunlight it decomposes to form silver and chlorine gas (hint: dark and white photography , photolysis ) I hope it will help you ?? Becoz it is an photo decomposition reactant and 2AgCl---->2Ag+Cl2 Silver salts are photosensitive compounds. So, when kept exposed to sunlight, it decomposes to form Silver metal. So, they are usually stored in dark coloured bottles. Because it reacts with sun light Silver chloride AgCl is sensitive to sunlight.when exposed to it,a salt decomposes into silver and chlorine. In order to check the decomposition, silver chloride is kept in dark coloured bottles so that sunlight may not fall on it. |

What are transparent, transmitted and opaque objects |
|
Answer» Transparent Objects : If you are able to see clearly through an object, it is allowing light to pass through it and is transparent. For example :water,clear glass etc. Opaque Objects : If we cannot see through an object at all, it is an opaque object. For example: wooden door, wall etc. Substances which allow light to pass through them are known to be TRANSPARENT. Eg :- Glass, water, etc. Substances which PARTIALLY allow light to pass through them are considered to be TRANSLUCENT. Eg :- Oily paper, tissue, etc. Substances which does not allow light to pass through them are called OPAQUE SUBSTANCES. Eg :- Clay, wood, etc. |

Why respiration considered an exothermic reaction |
|
Answer» During respiration our body\'s glucose gets react to oxygen to form CO2 ans h2o with heat energy as in photosynthesis co2 ,h20 and heat reacts to form c6h12o6 and co2 that\'s why respiration is known as exothermic reaction as well as the opposite of photosynthesis Respiration is considered as an exothermic reaction because energy is released in this process. Glucose combines with oxygen present in our cells to form CO2 and H2O along with energy. Carbohydrates present in food are broken down to form glucose. This glucose combine with oxygen in the cells of our body and provides energy. This reaction is known as respiration, hence, it is considered as an exothermic reaction. |

Why does the sun appear white at noon , why not any other instance |
|
Answer» Thanks At noon, the rays of sunlight have to travel comparitively lesser distance while passing through the earth\'s atmosphere and fall normal to the earth\'s surface. This causes the blue and violet lights to get scattered in a less intense manner along with the red lights. Thus, sun appears white at noon. But, at other instances, the distance increases increasing amount of scattering of blue and violet lights causing lights of longer wavelengths to reach our eyes. So, sun appears white ONLY at noon. |

How is food transport in plant ? |
|
Answer» Food is transport in plant through the process of translocation. The two sources of transferring food in plants are phloem and xylem .phloem transport food product which make plants itself in every part of the plants and xylem transports water and mineral to the every part of the plants. Food transport is through the process of translocation Phelom carries food from leaves to other part of the plant. Through an active process known as translocation. TRANSLOCATION is the process by which the soluble products of photosynthesis are bidirectionally transported to all parts of the plant. It requires energy. When energy is supplied to the phloem tissue, it becomes an area of higher concentration. This ensures that the soluble food reach areas of low concentration (where there is acute need for food) through simple diffusion from phloem tissue. |

What is cohesive force in reference with transpiration?? |
|
Answer» Thanks Aditya In tall plants, it is nearly impossible to bring water to the apical area through upward conduction by root pressure alone (it takes a long time). In such cases, transpiration plays the key role. As water is lost from the plant through transpiration especially during summers, naturally changes occur in the plant such that a particular form of suction force is produced which literally SUCKS the water up the xylem so that it reaches the topmost region. This is known as COHESIVE FORCE. |
