Physical Science in WB ANM GNM 2025 consists of several key chapters that must be studied well by the students. Few chapters have relatively higher weightage because they are repeatedly asked in the exam. We will guide you on which chapters to study first and which topics under each chapter are most important. In each chapter, you will also be able to see example questions for better understanding. Ready to dive into some major areas in Physical Science for your exam?

WB ANM GNM Physical Science Important Chapters 2025

The following are some of the important chapters from WB ANM GNM 2025 Physical Science with their important topics:

• Matter: Structure & Properties (States of matter, density, compressibility, atomic vs molecular structure)
• Thermal Phenomena (Heat & Energy) (Heat vs temperature, expansion, specific heat, conduction/convection/radiation)
• Behavior of Gases [ Gas laws (Boyle’s, Charles’s), ideal gas equation, pressure-volume relationship]

Let's dive into important Physical Science chapters one at a time. For easy preparation points, we've given some example questions so that you can practice easily.

Tips to Learn Matter: Structure and Properties

• Discuss real-life manifestations of solids, liquids, and gases (ice, water, steam).
• Work out formulas like Density = Mass ÷ Volume daily.
• Draw a simple diagram of an atom (electron, proton, neutron).
• Prepare flashcards listing properties of matter (shape, volume, compressibility).
• At least twice a week, review NCERT examples for improved recollection.

Example for Matter-Related Questions:

Learning Tips for Heat & Energy Chapter

• Reformulate this formula: Heat = Mass × Specific Heat × ΔT.
• Be able to understand examples of conduction, convection, and radiation.
• Attempt numerical sums on work, power, and energy.
• Understand and memorize the units: Joule, Calorie, Watt.
• Connect with real-life examples (heating elements, cooking, sunlight).

Heat and Energy Example Questions:

Prep Tips: Behavior of Gases

• Comprehend Boyle's Law and Charles's Law with illustrative graphs.
• Practice Ideal Gas Equation: PV = nRT.
• Relate to balloons, syringes, and a pressure cooker.
• Revise Pressure-Volume relationship.
• Maintain a quick notes page of laws with examples.

• Practice daily on ray diagrams.

Example Questions for Chapter Light and Sound

Atomic Structure & Periodicity Chapter Tips

• Draw the Bohr model for hydrogen and helium.
• Atomic number means protons, mass number means protons plus neutrons.
• Learn groups and periods in the periodic table.
• Memorize trends: atomic size, ionization energy.
• Prepare brief notes on the first 20 elements.

Example Questions

Mole Concept & Chemical Calculations / Acids, Bases & Salts Prep Tips

• Learn the formula - Mole = Given mass ÷ Molar mass.
• Performance practice on stoichiometric problems.
• Learn the pH scale: Acidic <7, Neutral =7, Basic >7.
• Examples to memorize: HCl, NaOH, and NaCl.
• Litmus Test: An acid turns blue litmus paper to red while a base turns red litmus paper to blue.
