Thermochemistry
As we are already acquainted with the principles that a chemical reaction is all about balance and the system equilibrium, this set of lessons will extend our knowledge base towards the exothermic and endothermic principles of chemical reactions.
Energy Basics
By the end of this section, the pupil shall be able to: Define energy, distinguish between its various forms, and describe the nature of energy changes that accompany chemical and physical transformations. Distinguish the related properties of heat, thermal energy, and temperature. Define and distinguish specific heat and heat capacity, and describe the physical implications of both. Perform calculations involving heat, specific heat, and changes in temperature.
Calorimetry
By the end of this section, the pupil shall be able to: Explain the scientific technique of calorimetry. Calculate and interpret heat and its related properties through the employment of typical calorimetry data.
Enthalpy
By the end of this section, the pupil shall be able to: State the first law of thermodynamics. Define enthalpy and explain its classification as a state function. Write and balance thermochemical equations. Calculate enthalpy changes for various chemical reactions. Explain Hess’s law and employ it to compute reaction enthalpies.
