NCERT Solutions of Class 9 Science Book Chapter Brief

Chapter 1: matter in our surrounding.

The Class 9 science textbook starts with the chapter “Matter in Our Surroundings”. Everything that we see around us is made up of material which is called matter. These things occupy space and have mass. Earlier, Indian philosophers had classified matter into 5 basic elements called Panch Tatva – air, water, earth, sky and fire. Now, modern scientists have come up with 2 types of classification, i.e., based on physical property and chemical nature. In this chapter, students will learn about the physical properties of matter .

The matter is made up of particles and these particulars are very small. The particles of matter have space between them, they are continuously moving and attract each other. The matter around us exists in 3 different states – solids, liquids and gases. These states of matter arise due to variation in the characteristic of the particles of matter. All the 3 states of matters have been explained in-depth with the help of activities. Further, the textbook explains that the state of matter is inter-convertible. The state of matter can be changed by changing temperature or pressure. The phenomenon of change of a liquid into vapour at any temperature below its boiling point is called evaporation. The rate of evaporation depends upon the surface area exposed to the atmosphere, the temperature, the humidity and the wind speed. Evaporation also causes cooling.

Topics Covered in Class 9 Science Chapter 1 Matter in Our Surrounding :

Definition of matter; solid, liquid and gas; characteristics – shape, volume, density; change of state – melting (absorption of heat), freezing, evaporation (cooling by evaporation), condensation, sublimation.

A great deal of variety can be found among the various living organisms as you look around. Diversity in Living Organisms is the 7th Chapter in NCERT Science Class 9 Solutions. This chapter explains the hierarchy of plant and animal kingdoms as well as the classification system. The differences between them and their ways of life are explored in this chapter.

Every organism is unique in itself. The multitudes of life forms that surround us have evolved on the earth over millions of years.Some of the bacteria may be a few micrometres in size, while there are blue whales and red wood trees of California having an approximate size of 30 metres and 100 metres respectively.

Some pine trees live for thousand of years while insects like mosquitoes die within a few days.It is practically not easy to study and know about different organisms.

NCERT Solutions for Class 9 Science Chapter 8 -Motion

Chapter 8 of NCERT Science introduces you to Physics, covering uniform and non-uniform motion, speed, and direction. By grasping these concepts, you’ll be equipped to comprehend that everything on Earth is in motion as the planet keeps rotating.

In every day life, we see that many objects are stationary while others keep on changing their position.We can see beautiful birds flying and fishes swimming in water. Atoms, molecules, planets, comets, stars and galaxies are all moving. Many times, motion or change in position of an object cannot be seen directly but it can only be inferred through indirect evidence.

For example we know that air is moving when we see leaves moving but we cannot see it directly.Many times, motion is a complex phenomenon. The same object may appear to be moving for one person but may be stationary for the other. A person outside the car may see a car moving but two people inside the car may appear to be at rest with respect to each other.

Some objects move in a straight line while others move in a circular path.Let us study and try to solve these complexities of motion. Number of Questions in NCERT Class 9 Science Exercise for chapter-8 are 4 from Exercise-1 to 4 and having total Questions-27.

NCERT Solutions for Class 9 Science Chapter 9 – Force and Laws of Motion

You have already gone through the basics of Force in Class 8, and now you will get to explore this topic further. You will become familiar with balanced and unbalanced forces, gain insights into the three laws of motion, and understand the works of physicist Galileo Galilei. This chapter will surely boost your understanding of Force and Motion.

We have already read about motion of a body along a straight line in terms of its velocity, acceleration and distance travelled by the body in a particular time. But what is the cause behind this motion?In day to day life, we observe that some effort is required to put a stationary object into motion or to stop it.

So, to produce motion, the effort which is required is called as “Force”.In this chapter, we will study about different concepts that revolve around “Force” as well as laws that govern motion.Number of Questions in NCERT Class 9 Science Exercise for chapter-9 are 4 from Exercise-1 to 4 and having total Questions-30

NCERT Solutions for Class 9 Science Chapter 10 – Gravitation

In Class 9, you learned about Newton’s dilemma: why do apples always fall from a tree? This chapter of class 9 will help you understand the concept of gravitational force and its workings better.

The force of interaction between any two particles having masses m 1 and m 2 separated by a distance r is attractive and acts along the line joining the particles. where G is a universal constant having the same value for all pairs of particles. Its numerical value is 6.67 x 10 -11 Nm 2 /kg 2 .

The gravitational forces between two particles are an action – reaction pair. The first particle exerts a force on the second particle that is directed toward the first particle along the line joining the two.Similarly , the second particle exerts a force on the first particle that is directed towards the second particle along the line joining the two.

These forces are equal in magnitude but oppositely directed.Number of Questions in NCERT Class 9 Science Exercise for chapter-10 are 4 from Exercise-1 to 4 and having total Questions-28.

NCERT Solutions for Class 9 Science Chapter 11 – Work and Energy

This chapter will help you grasp the scientific notion of work and several kinds of energy. You will have to use your math skills to complete the numerical, however, they are quite simple if one understands them and solves them daily.

When a force acts on a body and it moves through a certain distance, work is said to be done. The concept of work is closely related to energy as more the energy spent, more is the work done. A person with more power can also do more work. Let us study these concepts.

Topics To be covered are- Work done by a force, energy, power, kinetic and potential energy, law of conservation of energy. Number of Questions in NCERT Class 9 Science Exercise for chapter-11 are 4 from Exercise-1 to 4 and having total Questions-24.

NCERT Solutions for Class 9 Science Chapter 12 – Sound

You must be familiar with different sounds and echoes. This chapter looks into the journey of sound from its source to your ears and other concepts like echo, reverberation, sound wave propagation, etc.

CBSE Class 9 Science Chapter 12 covers sound production, sound propagation, sound reflection, range of hearing, applications of ultrasound, and the structure of the human ear. There are also a few questions in the chapter which can be solved only after understanding the concepts. So students must grasp and study the chapter carefully. Topics covered in this chapter are- Nature of sound and its propagation in different media, the range of hearing in humans; the speed of sound, ultrasound; a reflection of sound, and echo.
