NCERT Solutions of Science - Class 10th (Physics, Chemistry and Biology) Science - Free PDF Download

Science textbook of Class 10th deals with the disciplines such as Physics, Chemistry, Biology
and Environmental Science as integrated. There is no sharp division made by the NCERT in the textbook. However, as per the examination point of view, we can divide this book into three parts Physics, Chemistry and Biology. Environment Science part is covered in the Biology syllabus. NCERT Solutions of each chapter is provided in the below list so that you'll never face any problem with any question. You can select your desired chapter from the list and start your learning.


The whole book is subdivided into four topics namely, Materials, The World of the Living, How Things Work, Natural Phenomena and Natural Resources or in the way of discipline we can state them in Chemistry, Biology, Physics and Environmental Science respectively. As previously stated, Environment Science part is covered in the Biology syllabus. So we have total three subjects in Science subject, Physics, Chemistry and Biology.

The first unit has total five chapters. The first chapter is about the chemical reactions and equations in which we will learn about the how to write chemical equations and balance them. Also, we will learn about the various types of chemical reactions. In the second chapter, we will learn about the various types of acids, bases and salts and their reactions with metals and non-metals. The third chapter will take us to the world of metals and non-metals where we will learn about their properties and reactions among them. The fourth chapter is about the carbon and its compounds where we will learn about the properties of carbons and chemical substances containing carbon. In the fifth chapter, we will learn about the classification of elements and their evolution.

The Second unit consists of four chapters that are from sixth to ninth. The sixth chapter is about the various life processes which human need for their survival. In the seventh chapter, we will talk about the parts of the human body which are engaged in control and coordination activities. The eighth chapter deals with reproduction activities in unicellular and multicellular organisms. The ninth chapter,we will learn how the offsprings look alike.

The third unit is How things works which have four chapters. In the tenth chapter, we will learn about light and its phenomena reflection and refraction in a detailed manner. The eleventh chapter is about the human eye and some optical phenomena in nature. The twelfth chapter deals with the electricity in which we will learn electric circuit and resistance. In the thirteenth chapter, magnetic effects of electric current and its applications.

The fourth unit has three chapters in it. The fourteenth chapters talk about the various sources of energy such as conventional and non-conventional sources. The fifteenth chapter is about our environment in which we will learn about the eco-systems, food chains and how human activities contribute in degrading its quality. The last chapter is about the conservation of natural resources.
