Unit VII:     Properties of Bulk Matter                                                                         

Chapter–9: Mechanical Properties of Solids

Stress-strain relationship, Hooke’s law, Young’s modulus, bulk modulus

Chapter–10: Mechanical Properties of Fluids

  • Pressure due to a fluid column; Pascal’s law and its applications (hydraulic lift and hydraulic brakes), the effect of gravity on fluid pressure.
  • Viscosity, Stokes’ law, terminal velocity, streamline and turbulent flow, critical velocity, Bernoulli’s theorem and its applications.
  • Surface energy and surface tension, angle of contact, excess of pressure across a curved surface, application of surface tension ideas to drops, bubbles and capillary rise.

Chapter–11: Thermal Properties of Matter

  •  Heat, temperature, (recapitulation only) thermal expansion; thermal expansion of solids, liquids and gases, anomalous expansion of water; specific heat capacity; Cp, Cv – calorimetry; change of state – latent heat capacity.
  • Heat transfer-conduction, convection and radiation (recapitulation only), thermal conductivity, qualitative ideas of Blackbody radiation, Wein’s displacement Law, Stefan’s law, Greenhouse effect.

 

Unit VIII:  Thermodynamics                                                                                            

 Chapter–12: Thermodynamics

  •  Thermal equilibrium and definition of temperature (zeroth law of thermodynamics), heat, work and internal energy. The first law of thermodynamics, isothermal and adiabatic processes.
  • The second law of thermodynamics: reversible and irreversible processes



Unit IX: Behaviour of Perfect Gases and Kinetic Theory of Gases

Chapter–13: Kinetic Theory

  • Equation of state of a perfect gas, work done in compressing a gas.
  • Kinetic theory of gases – assumptions, the concept of pressure. Kinetic interpretation of temperature; RMS speed of gas molecules; degrees of freedom, the law of equipartition of energy (statement only) and application to specific heat capacities of gases; the concept of the mean free path, Avogadro’s number.

Unit X: Oscillations and Waves                                                                            

 Chapter–14: Oscillations

  • Periodic motion – period, frequency, displacement as a function of time, periodic functions.
  • Simple harmonic motion (S.H.M) and its equation; phase; oscillations of a loaded spring- restoring force and force constant; energy in S.H.M. Kinetic and potential energies; simple pendulum derivation of expression for its period. Free, forced and damped oscillations (qualitative ideas only), resonance.

Chapter–15: Waves

Wave motion: Transverse and longitudinal waves, speed of a travelling wave, displacement relation for a progressive wave, principle of superposition of waves, reflection of waves, standing waves in strings and organ pipes, Beats.
