Applied Science AQA/Enthalpy

Setting Applied context
The knowledge of enthalpy changes and the applications of Hess’s Law are important in many areas of scientific research and industry. Biotechnologists develop new fuels such as biodiesel and must compare their energy values with other types of fuel. Development scientists working in the food industry analyse new products for their calorific value and these will also be checked by chemical analysts working for Trading Standards. Chemical engineers in industry will apply Hess’s Law to enable the calculation of enthalpies of reaction in order to determine and better understand the likely effect of reaction conditions on yields.

Exploration of key ideas (must be original text, not C&P) – level checked by AQA
In general, point students towards the approach to take, as opposed to just giving them information.
