SELINA Solutions for Class 8 Physics ICSE
Physics can be interesting for some while being intimidating for others. Regardless, it is a critical science subject that forms the foundation for knowledge, understanding, and future studies. While explanations from teachers might be perceived as having clarified your fundamentals, the correct results can only be known once you evaluate yourself.
The Concise Physics Class 8 textbook comes along with questions to help students. You can solve them and head to TopperLearning’s SELINA Physics Class 8 Solutions for evaluating yourself. Let us understand what you will be learning in each chapter and, hence, what will be assessed.

Chapter-Wise List for SELINA Solutions for Class 8 Physics
There are eight chapters in SELINA Class 8 Physics. Their constituents are:
Chapter 1: Matter
While Chemistry offers the first chapter as a matter of structure and chemical insights, Physics will give you a different view by diving into its interaction. Here, the chapter includes characteristics of matter, the concept of boiling, condensation, desublimation and more. It also covers states of matter and their interconversion.
Chapter 2: Physical Quantities and Measurement
Since there is a unit for measuring almost everything, you must get familiar with it. Therefore, here, you will get solutions to both theoretical and numerical problems related to force, density, and associated topics. For instance, it will include density in different objects and states, relative density, calculation of density and principle of floatation.
Chapter 3: Force and Pressure
This chapter in SELINA Concise Physics Class 8 encompasses atmospheric and liquid pressure, factors affecting them, standard value, thrust and its effect. It also introduces you to torque and the turning effect of force or torque.
Chapter 4: Energy
Here, you will get help with solutions to the concept of energy and work. You will revise your knowledge of forms of energy, measurement of both energy and work and the impact of different factors on them.
Chapter 5: Light Energy
Helping you visualise everything, the role of light is huge in our lives. Learn in SELINA Class 8 Physics Solution how it works by understanding refraction in different objects, dispersion of light, and its causes and effects. It also includes solutions for image formation through lenses and mirrors. You will also be introduced to terms related to the refraction of light and spherical mirrors.
Chapter 6: Heat Transfer
This chapter in Physics SELINA Class 8 is about the conversion of liquid into a vapour state and the contribution of heat in it. It includes the effect of heat and temperature on molecules and the expansion of gases, solids, liquids and substances. You will also assess yourself on heat, its unit and variation of density with temperature.
Chapter 7: Sound
As you have studied light, sound also holds scientific concepts that are ready to be explored. Therefore, here, the constituents are characteristics and properties of sound waves, as well as different important terms such as frequency, pitch, wavelength, and others. You will also get a representation of the sound wave while gaining insights into its production and propagation method.
Chapter 8: Electricity
The last chapter of ICSE Class 8 Physics Ch 8 provides knowledge on electrical energy, power, electric charge, conductors, insulators and household consumption. It also includes colour coding of wire, household electric circuits, Miniature Circuit Breaker (MCB), power ratings of applications, and precautions to be taken when handling electric equipment and sources.
The Class 8 ICSE Physics Chapter 8 also includes solutions to electric fuse, electroscope, metres, static electricity, charge transfer, power transmission, different types of charges and the interaction between them.
Why Use Concise SELINA Solutions for Class 8?
SELINA Physics Class 8 solutions are highly recommended for students to use. Here is why:
- Understand the art of writing descriptive answers. Go through the solutions and understand what needs to be included in an answer based on the type of questions.
- Find the right keywords or scoring parts of the answers to questions.
- Get step-wise insights into numerical questions to understand where you went wrong.
- Get another approach to numerical questions, which might be different from yours. Ponder over it for better clarity.

- Find diagrammatic explanations for questions.
- Use the solutions as last-minute revision notes for insights at a glance.
ICSE Class 8 Physics Frequently Asked Questions
Yes, many of the chapters will remain the same but with more deeper insights into the concepts. Hence, it is essential to clarify your fundamentals at present level to avoid messing up your studies later.
You can evaluate your answers from SELINA Physics Class 8 Solutions by first going through what you wrote, followed by what is available in solutions. You can compare the presence of keywords and the interpretation of both the answers. Penalise yourself in the absence of missing out on the important line and diagram.
In this situation, we recommend following your teacher’s way of marking the answers. However, in general, you do deserve partial marks for correct steps, but you will have to face deduction for wrong answers.
Diagrammatic representation is important in all science subjects. It not only helps teachers evaluate your knowledge but also helps you clearly understand the topic. You get clarity on why, what and how for the topic.
