Which of the following are matter? Chair, air, love, smell, hate, almonds, thought, cold, drink, smell of perfume Answer: Chair, air, smell, almonds, cold, colddrink, smell of perfume are matter. Question 2. Give reasons for the following observation: The smell hot sizzling food reaches you several metres away, but to get the smell from cold food you have to go close. Answer: When food is hot, diffusion is more. But in cold food diffusion is slow. Hence to get the smell from cold food we have to go close. Question 3. A driver is able to cut through water in a swimming pool. Which property of matter does this observation show? Answer: This observation shows that particles of matter have kinetic energy. Question 4. What are the characteristics of the particles of matter? Answer: The characteristics of particles are as follows: • Particles of matter have space between them. • Particles of matter are continuously moving. • Particles of matter attract each other. Question 5. The mass per unit volume of a substance is called density (density = mass /volume) Arrange the following in order of increasing density – air, exhaust from chimneys, honey, water, chalk, cotton and iron. Answer: air, water, exhaust from chimneys, chalk, cott...

Class 9 Science Matter in Our Surroundings Intext Questions (Solved) PAGE NO. 3 Question 1: Which of the following are matter? Chair, air, love, smell, hate, almonds, thought, cold, cold drink, smell of perfume. Answer: Anything that occupies space and has mass is called matter. Matter can exist in three physical states—solid, liquid, and gaseous. Chair and almond are forms of matter in the solid-state. Cold drink is a liquid state of matter. Air and smell of perfume are gaseous states of matter. Note: The sense of smell does not matter. However, the smell or odour of a substance is classified as matter. The smell of any substance (say, perfume) is the gaseous form of that substance which our olfactory system can detect (even at very low concentrations). Hence, ...

Hint: Density of a substance can be defined as the measure of its mass per unit volume. It is just the weight for a chosen amount or volume of the material. Complete step by step answer: We all know that as long as a substance is made of molecules it will have density and it can be given or defined as the mass divided by the volume of the substance. The average density of an object equals its total mass divided by its total volume. Now, from the definition of density we can say that an object that is made from a comparatively dense material such as iron will have less volume than an object equal in mass but which is made from some less dense substance such as water. Generally, liquids are much denser than the gases because the molecules of liquids are packed relatively closer to each other than in the gases and due to the same reason the density of solids is more than the density of the liquids because the molecules of solid are more tightly packed. It is also known that the material or the substance with lower density tends to float upon the substance with the higher density. In general, the volume of the liquid is known to be more than the volume of the solid. This is due to the fact that the particles of the liquid are more free to move and thus results in more volume. But, water in different forms tends to show an anomaly in this respect. The solid form of water, that is ice, floats on its liquid form, that is water itself. This is due to the fact that when water freez...
