NCERT Grade 11, Chemistry, Chapter 5, States of Matter: Gases and Liquids belongs to Unit 5. Students have learnt about the states of matter and their basic properties. This chapter, States of Matter: Gases and Liquids will provide a depth about the states of matter, their nature, reactivity, etc. Concepts such as Intermolecular Forces, Dispersion Forces or London Forces, Dipole - Dipole Forces, Dipole–Induced Dipole Forces, Hydrogen Bond, Thermal Energy, Intermolecular Forces Vs Thermal Interactions, The Gaseous State, The Gas Laws, Boyle’s Law (Pressure – Volume Relationship), Charles’ Law (Temperature – Volume Relationship), Gay Lussac’s Law (Pressure-Temperature Relationship), Avogadro Law (Volume – Amount Relationship), Ideal Gas Equation, Density and Molar Mass of a Gaseous Substance, Dalton’s Law of Partial Pressures, Kinetic Molecular Theory of Gases, Behaviour of Real Gases: Deviation From Ideal Gas Behaviour, Liquifaction of Gases, Liquid State, Vapour Pressure, Surface Tension and Viscosity are learnt through this chapter.
After studying this unit students will be able to explain the existence of different states of matter in terms of balance between intermolecular forces and thermal energy of particles; explain the laws governing behaviour of ideal gases; apply gas laws in various real life situations; explain the behaviour of real gases; describe the conditions required for liquifaction of gases; realise that there is continuity in gaseous and liquid state; differentiate between gaseous state and vapours; and explain properties of liquids in terms of intermolecular attractions.NCERT Grade 11, Chemistry, Chapter 5, States of Matter: Gases and Liquids holds a weightage of 21 marks in combination with Unit 4, Unit 5, Unit 6 and Unit 7.
