Class 6 – Chemistry | A – 6 Nature of Matter 1 1. Nature of Matter Solutions Classification of Matter LEVEL-I 1. Correct option: (C) Anything that has some mass and occupies space is called matter. The quantity of matter present in an object is mass. 2. Correct option: (D) Sun, the rays of the sun emit energy in the form radiation. 3. Correct option: (A) Solids are rigid having definite shape and volume 4. Correct option: (C) Solids, liquids and gases are called the three states of matter. 5. Correct option: (A) In three states of matter, gases have neither definite shape nor definite volume. 6. Correct option: (C) The maximum intermolecular force of attraction observed in solids because of closely packing. 7. Correct option: (B) The liquid molecules can move freely because, the molecules are packed loosely. 8. Correct option: (A) A) Solids have definite volume and shape. B) Liquids have definite volume and indefinite shape. C) Intermolecular force of attraction in solids is high. 9. Correct option: (B) The liquid state of matter has definite volume and no definite shape. 10. Correct option: (B) The gas has negligible intermolecular force of attraction because of very loose packing of molecules. 11. Correct option: (C) Gas has the property of flowing in all directions. Because of that we smell the fragrance of Perfumes, flowers etc. 12. Correct option: (C) A) Liquids take the shape of vessel in which it present. So, it does not have definite shape. B) Liquids have definite volume. C) Liquids can be compressed slightly because of loosely packing and intermolecular space. D) Liquids have more intermolecular force of attraction compared to gases because of close packing.
