What are the characteristics of matter.? describe any 2 with activity..
Answers
Answer:
A matter is anything that has mass and occupies space. Pen, paper, clips, sand, air, ice, etc. are different forms of matter. Every matter is made up of tiny particles. These particles are so tiny that they can’t be seen with naked eyes. Let’s learn about the different characteristics of particles of matter.
Characteristics of Particles of Matter
As mentioned earlier, every substance is made up of particles. These particles exhibit some characteristics. They can influence the state and properties (physical and chemical) of a substance. The three characteristics shown by particles of matter are as follows.
Explanation:
Physical Properties Of Matter
Since a long time, scientists have been researching about chemical and physical properties of matter. In simple terms, they define matter as something which has mass and occupies space (that is volume). Hence everything we see around us is matter. For example, stars that twinkle, the sun that shines, the food we eat, bricks we use to make buildings, water in oceans and rivers, rocks that form mountains, etc. All of these can be brought under a single umbrella called matter. But does all the matter that we see exhibit the same physical properties? Obviously not, a block of wood is continuous while sand particles are coarse. Similarly, salt particles are soluble in water while sand particles are not. All these properties are known as physical properties. Let us learn some of the physical properties through an activity.
Let us take 5-6 crystals of potassium permanganate and dissolve them in 300 ml of water.
Pour out 20 ml of this solution into a 100 ml of pure water present in another beaker.
Repeat the above procedure by again taking out 20 ml of the above solution and pouring it into 100 ml of pure water present in another beaker.
Keep on repeating this procedure by diluting the solution like this 8 to 10 times.
Observe the color of the last solution.
Physical Properties of Matter
Addition of potassium permanganate to water
We observe that the solution in the last beaker is light pink in color. Thus we can conclude that even a very small amount of potassium permanganate is able to change the color of the solution. Thus, we can say that matter can be broken into millions of tiny pieces further. This piece is indestructible in nature.

All matter has mass and occupies some space.
