The text defines mixtures as combinations where each component retains its properties and does not react chemically. It distinguishes non-uniform mixtures, whose components are visible, from uniform mixtures where components are evenly distributed and cannot be separated even with a microscope.

 \n● How can elements be combined to form a compound?  \n● How could the discovery of a compound that absorbs carbondioxide from the air contribute to solving environmentalchallenges?  \n● Share your questions  \nHave you ever wondered what the world around you is madeof?Look around!The staircase you use,the air you breathe,thewater in your bottle,the food in your lunch box,the clothes andshoes you wear,the book youread,the trees outside,the ball youplay with and even the stick you carry—all of these are examplesof matter,which you have learnt in earlier grades.  \nYou have also learnt that all these things are made up of tinyparticles.Most of the things around us are not made of just onesubstance;rather they are made up of two or more substancesmixed together.Let us now understand how different substancescome together to form mixtures.  \n# 8.1 What Are Mixtures?\n\nHave you ever wondered what makesyour poha(Fig.8.1)so delicious or howto make the perfect sprout salad?Whilethese dishes mayseem very different,theyshare something in common—they areboth made by mixing several ingredients.We observe the mixing of substances ineveryday life.Sugar dissolved in wateris also a mixture,and so are soups andlemonade.  \nFig.8.1:Poha  \nWhen two or more substances aremixed,where each substance retainsits properties,it is called a mixture.The individual substances that make upa mixture are called its components.The components of a mixture do notreact chemically with each other.In somemixtures,the components—like greengram,chickpeas,onion,and tomatoin a sprout salad (Fig.8.2),are easy tosee.Such mixtures,where the different  \nFig.8.2:Sprout salad  \ncomponents are generally visible with the naked eye or with amagnifying device,are non-uniform in nature.Can you identifya few more examples of non-uniform mixtures around you?  \nOn the other hand,some mixtures have components thatcannot be seen separately even with the help of a microscope.For example,sugar and water particles cannot be seen separatelyin their mixture.Such types of mixtures,where the componentsare evenly distributed and cannot be distinguished,are uniformin nature(Fig.8.3).Can you list a few uniform mixtures?  \nFig.8.3:Uniform mixtureof sugar and water  \nDoyouknow that stainless steelis also amixture?Stainless steel contains iron,nickel,chromium,and a small amount of carbon.They are mixedso uniformly that the entire mixture appearsthe same throughout and one cannot see theindividual substances.Such mixtures are knownas alloys.Brass,a mixture of copper and zinc,  \nand bronze,a mixture of copper and tin,are Fig.8.4:Utensils made of        some other examples of alloys(Fig.8.4).             stainless steel,brass,and bronze  \nOur scientific heritage  \nMishraloha was the name given to the mixture of two or more metalsthat had properties distinct from its constituent metals.AncientIndian texts,such as the Charaka Samhita,Susruta Samhita,RasaratnaSamucchaya,Rasa Jala Nidhi,etc.,mention the use of alloys formedicinal purposes.For example,Bronze,also known as Kamsya,isan alloy made up of Copper(Tamra,4 parts)and Tin(Vanga,1 part),was used to improve digestion and boost immunity.  \n## 8.1.1 Is air a mixture?\n\nIn Curiosity,Grade 6,you learnt about air and its composition inthe chapter 'Nature's Treasures'.Is air a mixture?What kind ofmixture is it?  \nYou have learnt that air is a uniform mixture of mainlynitrogen,oxygen,argon,carbon dioxide,and water vapour.Out ofthese,oxygen is required by most of the living beings to stay alive.It also helps in combustion.Nitrogen,which constitutes about 78%of the air,does not take part in combustion.We also learnt that airhas water vapour in it.When warm air touches a cool surface,thewater vapour turns into liquid water,forming tiny droplets.Recallthe experiment where you tested the presence of carbon dioxidein the air that we exhale.Let us confirm the prese","cbCaibD7m217Uu1O","https://ap.wps.com/l/cbCaibD7m217Uu1O","pdf",3401991,18,"English","# 8.1 What Are Mixtures?\n## 8.1.1 Is air a mixture?\n## Activity 8.1: Let us experiment\n## Activity 8.2: Let us explore\n## A step further","[{\"question\":\"What makes a mixture different from other combinations of substances?\",\"answer\":\"In a mixture, two or more substances combine while each substance retains its properties.
