Class 9 Science Chapter 2 Is Matter Around Us Pure introduces us to the idea that not all matter is the same, and that the substances around us can be classified into different types based on their purity.<\/p>\n<p>Matter can either be a pure substance, like elements and compounds, or a mixture. You\u2019ll learn about how these mixtures can be either homogeneous (uniform throughout) or heterogeneous (non-uniform), and how they can be separated through different methods. This chapter is important because it helps us understand the basic differences between pure substances and mixtures, setting the foundation for more advanced topics in chemistry.<\/p>\n<p>In this Class 9 Science Chapter 2 Is Matter Around Us Pure quiz, you&#8217;ll get a chance to test your understanding of these concepts. So, let\u2019s dive in, challenge your mind, and strengthen your grasp of the building blocks of matter!<\/p>\n<p><strong>Class 9 Is Matter Around Us Pure Quiz 1 Rules<\/strong><\/p>\n<ul>\n<li><strong>Time Limit<\/strong>: You have <strong>15 minutes<\/strong> to complete this quiz.

In an aqueous solution of sugar, solute is sugar and solvent is water. Formation of solution is a physical process. Formation of an aqueous binary solution may be exothermic or endothermic.<\/p>\n<\/details>\n<p><strong>Question 3: Into how many types is matter classified on the basis of composition and properties?<\/strong><\/p>\n<p>a) 1<br \/>\nb) 2<br \/>\nc) 3<br \/>\nd) 4<\/p>\n<details>\n<summary><strong>Answer:<\/strong><\/summary>\n<p>The correct answer is <strong>b) 2.<\/strong><\/p>\n<p>Matter can be classified into two main types on the basis of composition and properties: pure substances and mixtures (impure substances). Pure substances are further classified into elements and compounds. Mixtures are further classified into homogeneous and heterogeneous mixtures.<\/p>\n<\/details>\n<p><strong>Question 4: The substances which have a definite chemical composition and definite chemical and physical properties are called _________ substances.<\/strong><\/p>\n<p>a) pure<br \/>\nb) impure<br \/>\nc) mixtures<br \/>\nd) solutions<\/p>\n<details>\n<summary><strong>Answer:<\/strong><\/summary>\n<p>The correct answer is <strong>a) pure.<\/strong><\/p>\n<p>The substances which have a definite chemical composition and definite chemical and physical properties are called pure substances. Pure substances are further classified as elements and compounds. For example, gold, silver, water, sodium chloride, etc.<\/p>\n<\/details>\n<p><strong>Question 5: Is it true that substances that have a definite chemical composition and definite chemical and physical properties are called pure substances?<\/strong><\/p>\n<p>a) True<br \/>\nb) False<\/p>\n<details>\n<summary><strong>Answer:<\/strong><\/summary>\n<p>The correct answer is <strong>a) True.<\/strong><\/p>\n<p>The given statement is true.

Pure substances are further classified as elements and compounds. Gold and oxygen are examples of elements. Sodium chloride is an example of a compound. Air is a mixture of two or more gases present in any proportion. So it is not a pure substance.<\/p>\n<\/details>\n<p><strong>Question 9: Which of the following is an example of a pure substance?<\/strong><\/p>\n<p>a) Air<br \/>\nb) Salt solution<br \/>\nc) Water<br \/>\nd) Sugar solution<\/p>\n<details>\n<summary><strong>Answer:<\/strong><\/summary>\n<p>The correct answer is <strong>c) Water.<\/strong><\/p>\n<p>The substances which have a definite chemical composition and definite chemical and physical properties are called pure substances. Air, salt solution, and sugar solution consist of two or more components mixed in any proportion. So they are not pure substances. Water is made up of hydrogen and oxygen combined in a fixed ratio of 1:8. So it is an example of a compound and thus a pure substance.<\/p>\n<\/details>\n<p><strong>Question 10: Elements are classified into ________ types.<\/strong><\/p>\n<p>a) 1<br \/>\nb) 2<br \/>\nc) 3<br \/>\nd) 4<\/p>\n<details>\n<summary><strong>Answer:<\/strong><\/summary>\n<p>The correct answer is <strong>c) 3.<\/strong><\/p>\n<p>Elements are pure substances that cannot be converted into anything simpler than themselves by any physical or chemical process.
