define enthalpy, and distinguish between CP and CV
recognise and define the enthalpies of solution, formation, atomization, vapourization, condensation, fusion, sublimation and combustion
use Hess’s Law to calculate the enthalpy of an unknown reaction from appropriate data, including standard enthalpies of formation, or estimate it from bond enthalpies
define heat engine, thermodynaic cycle, and the efficiency of a heat engine
recognise the difference between petrol and diesel engine cycles
recognise and distinguish common fuel types, and discuss their advantages and disadvantages in different situations.
define entropy, spontaneous processes and equilibrium
use standard entropies to calculate ΔS for a reaction at standard conditions, and with standard enthalpies of formation, predict whether a reaction will be spontaneous under those conditions
