Stainless steel is very useful material in our life. In stainless steel, iron is mixed with Correct Answer Ni and Cr

Concept - 

Alloys:

  • Alloys are metal mixtures with additional elements whose precise composition is dictated by the qualities required.
  • They are metallic in nature, which means they have strong thermal and electrical conductivity.
  • Alloys are metal alloys or metal alloys with additional elements.
  • Other metals/elements can be added to metals in certain ratios to make alloys that give specific properties or strengthen some of the metals' existing properties.
  • In simple terms, an alloy is a homogenous blend of two or more metals, or a metal and a non-metal.
  • Examples -
  1. Steel 
    • Steel is a very popular alloy because of its inexpensive cost and great tensile strength.
    • It is an alloy made up of iron(Fe) and carbon(C).
  2. Bronze 
    • Bronze is a copper(Cu) and tin(Sn) alloy.
    • Medals, coins, trophies, hefty gears and tools, and several types of electrical devices all employ it.
  3. Nichrome 
    • Nichrome is an alloy made mostly of nickel(Ni) and chromium(Cr).
    • Resistance wires are the most common use of nichrome.
    • Certain electrical equipment, such as space heaters and bread toasters, employ it as the heating element.
  4. Brass 
    • Brass is a copper-zinc alloy with variable proportions of copper(Cu) and zinc(Zn) to obtain different mechanical, electrical, and chemical properties.
    •  It's also been commonly utilized for utensils of many kinds.
    • Because of its dazzling gold-like appearance, brass has long been a desirable decorative material.
  5. Stainless Steel 
    • It is an alloy of iron(Fe), Nickel(Ni), and chromium(Cr). 
    • Utensils are made from stainless steel.
    • This alloy does not undergo rusting. 

Explanation - 

  • Stainless steel does not undergo rusting. 
  • It is an alloy of - iron(Fe), Nickel (Ni), and Chromium (Cr).
  • It has a wide range of applications it is used in Buildings, to make utensils, and sometimes jewellery.
  • Hence, the correct answer to this question is - Nickel(Ni) and Chromium(Cr).
    • It is made up of iron mixed with nickel and chromium.

S6: Psychologists have studied these forces in depth.

The Proper sequence should be:

In two types of stainless steel the ratio of chromium and steel are 2 : 11 and 5 : 21 respectively. In what proportion should the two types be mixed so that the ratio of chromium to steel in the mixed type becomes 7 : 32 = ?
Read the paragraph and answer the question that follows: Initially, theatres were the only way to get access to the cinema but with the popularity of television and cable TV, watching movies became easier. With the advent of the internet and mobile phones, we now get access to the cinema on our mobile screens and can watch them just about anywhere and anytime. Everyone today is more or less connected to the cinema. When we see certain incidences shown in movies that we can relate to we naturally let them influence our mindset and thought process. We even idealize certain characters and scenarios from the movies. We want our personality and life to be just like the life of the movie character we idealize. Some people get so hooked on to these characters that they become an integral part of their life. Certain incidences shown in movies never influence our mindset. Is this statement true or false?

Read the following passage and answer the item that follows. Your answers to this item should be based on the passage only. We live in digital times. The digital is not just something we use strategically and specifically to do a few tasks. Our very perception of who we are, how we connect to the world around us, and the ways in which we define our domains of life, labour and language are hugely structured by the digital technologies. The digital is everywhere and, like air, invisible. We live within digital systems, we live with intimate gadgets, we interact through digital media, and the very presence and imagination of the digital has dramatically restructured our lives. The digital, far from being a tool, is a condition and context that defines the shapes and boundaries of our understanding of the self, the society, and the structure of governance. Which among the following is the most logical and essential message conveyed by the above passage?

A: Iron is able to take on two crystalline forms (allotropic forms), body-centered cubic, and face-centered cubic, depending on its temperature.  B: Iron is the base metal of steel. C: Because of steel's high tensile strength and low cost, this material is best used in buildings, infrastructure, tools, ships, trains, cars, machines, electrical appliances, and weapons. D: Steel is an alloy of iron and carbon and, sometimes, other elements such as chromium.
