In this topic,Student should be able to :
a) Understand gaseous state with reference to: i) Postulates of kinetic molecular theory ii) Gas laws: Boyle’s law, Charles’ law, Avogadro’s law and gas equation (PV=nRT) and calculations involving gas laws. iii) Deviation of real gases from ideal behaviour at low temperature and high pressure’ iv) Conditions necessary for gasses to approach ideal behavior.
b) Discuss liquid state with reference to: Evaporation, vapour pressure, boiling and hydrogen bonding in water.
c) Explain the lattice structure of a crystalline solid with special emphasis on: i) Giant ionic structure, as in sodium chloride.ii) Simple molecular, as in iodine. iii) Giant molecular, as in diamond; silicon (IV) oxide. iv) Hydrogen-bonded, as in ice.
d) Outline the importance of hydrogen bonding to the physical properties of substances, including NH3, H2O, C2H5OH and ice.
e) Suggest from quoted physical data the type of structure and bonding present in a substance
