Write short notes-polyester and polyamide.Answer the given question pointwise. |
|
Answer» Fibers are the building blocks of textile materials and there is a strong correlation between the fiber properties and properties of resultant textile products. The major end-use application of textile fibers is its use in apparel fabrics. Invention of synthetic fibers especially polyamide and polyester and fiber engineering can PRODUCE, modify, and tailor fibers in ways far beyond the PERFORMANCE limits of fibers drawn from SILKWORM cocoon, grown in the fields or spun from the fleece of animals. Polyester fiber has good easy care properties and polyamide fibers have better elastic properties. The yarns are either woven or knitted to develop fabrics. Today's apparel fabric maximizes enjoyment and comfort in indoors as well as outdoors and in any kind of weather. Waterproof, windproof, and breathable through different finishing PROCESSES are just a few of many properties in demand. Therefore, stretch properties can be imparted to polyamide fibers using textured nylon in combination with ELASTANE yarns. Certain desired properties can be built into polyester and polyamide fibers during production. However, polyamide seems to be losing its share to polyester, overwhelmed by sheer volume if not performance. Many woven industrial and apparel fabrics seem to favor polyester. Polyamide's dyeability is an advantage, but not sufficiently so to overcome the supply and variants available in polyesterI hope it is helpfulmark it as brainliest ans know pls pls pls pls |

Define pressure for the applied force. If the area increases or decreases, then that will be the change in pressure ? Explain and give proper illustrations. |
|
Answer» Pressure is the force exerted per unit AREA. Mathematically Pressure is directly PROPORTIONAL to the applied force and inversly proportional to the area (i.e. If we increase the area the pressure decrease and if we increase the force the pressure increase).Explanation:In your practical life we use knife instead of spoon for cutting this is because the area of the sharp side of knife is less than that of spoon THUS it applies more pressure on the object to cut, and hence as the sharpness of knife increase the cutting can be done more easily; by APPLYING less force.Another EXAMPLE is when you nail into a wall the thinner the nail is the lesser is the force required to push it into the wall this is because the thin nail has a very small TIP area and thus it produce more pressure as compared to a large (thick) nail. |

Write in brief about reaction of electrolysis of water. By which apparatus the study of electrolysis of water can be studied ? |
|
Answer» The word Electro MEANS electricity and Lysis means splitting thus the term Electrolysis means splitting of a compound using electricity (current).This is done by dissolving the compound (which is usually polar) in a solvent to form a solution and then a negative and a positive plate is dipped in it which with the help of voltage provided by a battery cause the lysis (splitting) of the compound (molecules).Explanation:You can PERFORM a simple experiment to illustrate electrolysis at home or school lab all you need are .:1) A pot/beaker made of glass or plastic2) Two small plates of iron/copper/aluminium (conducting material)3) Two wire and a common cell or small battery (EVEN yoi can use your phone battery) but be careful of short-circuiting4) Water and table-salt (NaCl)First of all dissolve some salt in water in the pot or beaker.Next attach each end of a wire to the battery and metal plate.Now dip the metal plates in the solution and you would notice bubble formation (which is Chlorine gas liberating at anode or positive terminal) while the sodium would deposit at cathode or negative terminal. |

Explain only the electronic configuration covalent bond formation in the structure of chlorine molecule. |
|
Answer» t BONDS are the bonds formed between TWO atoms by mutual sharing of electrons to complete the octate. In a Chlorine molecule, the atom has SEVEN electrons in the outermost shell. So, it shares one electron with another chlorine atom. This electron circles around both the atoms. What it means is, one atom of chlorine, SAY a₁, shares an electron which circles around both the atoms and the other atom, say a₂, shares one electron which circles around both the atoms. In this way the octate of both of them is completed.Hop this helps you. |
