Chapter-Wise Key Questions
In the Class 10 CBSE Science exams, understanding the essential questions from each chapter can significantly enhance your preparation and scoring potential. This section categorizes key questions into three main segments: Physics, Chemistry, and Biology. By focusing on these frequently asked questions, students can ensure they cover the most critical topics necessary for high scores.
Physics
Physics often involves conceptual understanding and application-based questions. Some of the most important questions include:
Light - Reflection and Refraction: Explain the laws of reflection. How do you derive the mirror formula?
Electricity: Define Ohm's Law. How do you calculate the equivalent resistance in series and parallel circuits?
Magnetic Effects of Electric Current: Describe the principle and working of an electric motor.
Sources of Energy: What are the advantages and disadvantages of using solar energy?
Chemistry
Chemistry questions often test your understanding of reactions, chemical equations, and periodic properties. Key questions include:
Chemical Reactions and Equations: What are the different types of chemical reactions? Provide examples.
Acids, Bases, and Salts: How do you distinguish between strong and weak acids? Discuss the pH scale.
Metals and Non-Metals: Explain the reactivity series of metals. How do you extract metals from their ores?
Carbon and its Compounds: Illustrate the structure of methane and ethane. What are isomers?
Biology
Biology questions predominantly focus on life processes, genetics, and the environment. Important questions are:
Life Processes: Describe the process of photosynthesis. How does human digestion work?
Control and Coordination: Explain the function of hormones in human beings.
Heredity and Evolution: What is Mendel's law of inheritance? How do fossils provide evidence for evolution?
Our Environment: Discuss the impact of human activities on the environment. What are biodegradable and non-biodegradable substances?
By focusing on these key questions, students can streamline their study process, ensuring they cover the most significant topics across Physics, Chemistry, and Biology. This targeted approach will not only help in better retention of concepts but also maximize their scoring potential in the exams.
