Matter-Its Nature and Behaviour

This chapter explains the states of matter with differences between the three of them. Melting and boiling points, latent heat, effects of temperature and pressure on the matter are also discussed here with their standard units.

This chapter explains the different states of matter and their types. It also describes their characteristics, properties of compounds, mixture, elements, metals, non-metals, metalloids and solution.

In this chapter, we will learn the concepts of atoms and molecules, definitions of laws and atomic theory that defines all the matter in terms of atoms and properties. The concepts of atomicity, moles, molecular and atomic mass are also discussed here.

This chapter explains the structure of the atom with its postulates and drawbacks by various models suggested by J.J. Thomson, Ernest Rutherford and Neil Bohr. It also defines valency, atomic and mass number, isotopes and isobars.
