====== Chapter 17: Physics of Solids ======
This is a seventh chapter of the book Physics 12 published by Punjab Curriculum and Textbook Board, Lahore, Pakistan.

After studying this chapter, the students will be able to:

  * Distinguish between the structure of crystalline, glassy, amorphous and polymeric solids.
  * Understand the idea of lattice.
  * Appreciate that deformation is caused by a force and that, in one dimension, the deformation can be tensile or compressive.
  * Define and use the terms Young's modulus, bulk modulus and shear modulus.
  * Describe an experiment to determine elastic limit and yield strength.
  * Distinguish between elastic and plastic deformation of a material.
  * Synthesize and deduce the strain energy in a deformed material from the area under the force extension graph.
  * Describe the energy bands in solids.
  * Classify insulators, conductors, semi-conductors on the basis of energy bands.
  * Distinguish between intrinsic and extrinsic semiconductors.
  * Explain how electrons and holes flow across a junction.
  * Describe superconductors.
  * Distinguish between dia, para and ferro magnetic materials.
  * Understand and describe the concept of magnetic domains in a material.
  * Know the Curie point.
  * Classify hard and soft ferro magnetic substances.
  * Understand hysteresis and hysteresis loss.
