## Karnataka State Board Class 5 EVS Chapter 11 Nature of Matter

### Class 5 EVS Nature of Matter Text Book Questions and Answers

Question 1.
What is matter?
Matter is anything that occupies space and has weight.

Question 2.
State the properties of matter.
Properties of matter are:

• Matter occupies space.
• Matter has weight.

Question 3.
How can you prove that matter occupies space?
Place a glass beaker completely filled with water on a plate. Immerse a stone tied to a thread slowly into the beaker. Some water in the beaker flows out and collects in the plate.

Question 4.
Name the three forms of matter.
The three forms of matter are solids, liquids, and gases.

Question 5.
Think and group these materials in their particular column:
[butter milk, candle,- curd, kerosene, charcoal, honey, piece of brick, smoke.]

 Solid Liquid Gas Piece of brick candle buttermilk kerosene honey smoke charcoal

Question 6.
Fill in the blanks with suitable words

1. Ice cube on heating water
2. Water on heating vapor
3. vapor on cooling water
4. water on cooling Ice

Question 7.
Write two factors that density depends.
The density depends on two factors:

1. Mass of each particle.
2. Compactness of arrangement of these particles.

Question 8.
Mention the other classification of matter.
The other classifications of matter are

1. Elements
2. Compounds and
3. Mixtures.

Question 9.
Explain buoyancy.
When an object is immersed in water, it exerts a downward force on water and the water, in turn, exerts an upward force or upthrust on the objects. The upthrust is equal to the mass of the liquid displaced. It is this upthrust that keeps a body afloat. This upthrust is called the force of buoyancy.

3. The SI unit of density is
4. The elements are classified into metals and nonmetals.
5. Mass is the quantity of matter in a given object (or) a substance.
6. Pressure is the force exerted on a unit area.
7. Volume is the amount of space occupied by matter.
8. Plasma is the fourth state of matter.
9. Visible matter is made up of invisible particles.

Question 1.
How are the particles arranged in solids and liquids?
In solids, particles are help together closely in a compact manner, in liquids, the particles are close together but they are ot arranged in an order as in case of solids.

Question 2.
Gases have no definite shape and volume. Why?
Gas particles in a container move independently in all directions and so it has no definite shape or volume.

Question 3.
What is sublimation?
The change of stae from solid to vapour or from vapour tosolid without passing through the liquid state is called sublimation.

Question 4.
State the law of conservation of matter
