1. OBJECTIVE QUESTIONS, · Reason : Competetivenes of manufacturing industry has helped in increasing their production and also made production process efficient. Ans : (a) Both assertion and reason are true and reason is the correct explanation of assertion. The reason justifies the 4.Process manufacturing, · Process manufacturing is a branch of manufacturing that is associated with formulas and manufacturing recipes, and can be contrasted with discrete manufacturing, which is concerned with discrete units, bills of materials and the assembly of components. Process manufacturing is common in the food, beverage, chemical, pharmaceutical ...What Is Malleability in Metal?, · Copper is an example of a metal that has both good ductility (it can be stretched into wires) and good malleability (it can also be rolled into sheets). While most malleable metals are also ductile, the two properties can be exclusive.Single crystal, · A single-crystal, or monocrystalline, solid is a material in which the crystal lattice of the entire sample is continuous and unbroken to the edges of the sample, with no grain boundaries. The absence of the defects associated with grain boundaries can give monocrystals unique properties, particularly mechanical, optical and electrical, which ...What Is Distillation? Principles and Uses, · Distillation is the process of separating components of a mixture based on different boiling points. Examples of uses of distillation include purification of alcohol, desalination, crude oil refining, and making liquefied gases from air. Humans have been using distillation.
Wire drawing, · Wire drawing is a metalworking process used to reduce the cross-section of a wire by pulling the wire through a single, or series of, drawing die(s). There are many applications for wire drawing, including electrical wiring, cables, tension-loaded structural components, springs, paper clips, spokes for wheels, and stringed musical instruments ...Copper Production: How Is Copper Made?, · Copper processing is a complex process that involves many steps as the manufacturer processes the ore from its raw, mined state into a purified form for use in many industries. Copper is typically extracted from oxide and sulfide ores that contain between 0.5 and 2.0% copper.Van Arkel's process to Refine Titanium/ Zirconium, · Electrolytic refining of copper class 10&12 - Duration: 9:46. Seema Makhijani 125 views 9:46 Test for cobalt ions cation analysis - Duration: 6:22. Seema Makhijani 11,919 views ...What Are the Advantages and Disadvantages of Copper?, · Copper is also the primary component of bronze, which played an important historical role. Bronze has a number of practical qualities, but it has largely been replaced by steel, which is stronger and cheaper to produce. Bronze has been relegated to artistic use. ...Manufacturing of Sulfuric acid by Contact process, · Almost all sulfuric acid is manufactured by the contact process. Properties Molecular formula : H2SO4 Molecular weight : 98.08gm/mole Appearance : Water white slightly viscous liquid Boiling point : 2900C Melting point : 100C Density : 1.840gm/mL (liquid) Solubility : Miscible with water in all proportions Viscosity : 26.7cP (200C) Aqueous sulfuric acid solutions are defined by their H2SO4 ....
Etching (microfabrication), · Etching is used in microfabrication to chemically remove layers from the surface of a wafer during manufacturing. Etching is a critically important process module, and every wafer undergoes many etching steps before it is complete. For many etch steps, part of the wafer is protected from the etchant by a "masking" material which resists ...Industry of Pakistan, · Mining and quarrying The country has immense reserves of various minerals and natural resources. Important minerals found in Pakistan are gypsum, limestone, chromites, iron ore, rock salt, silver, gold, precious stones, gems, marble, copper, coal, graphite, sulphur, fire clay, silica..
