Combustion of Alcohols Purpose: The purpose of this investigation is to use calorimetry to determine the molar enthalpy change in the combustion of each of a series of alcohols. Question: How do the enthalpies of combustion change as the alcohol molecules become larger? Prediction: I predict the bigger the molecule the more the energy will be released. Materials: On lab sheet Procedure: On lab sheet Observation: On other page Analysis: b) i) Ethanol – q=(100g)(4.18J/g/C)(25.5C) q=10659J

Self Heating Food and Drink Cans Heater meals – originally developed for military use – are ready-made self-heating meal packs. They can be heated in many ways – by pressing a button on the packaging‚ unwrapping and shaking the pack‚ or pouring the contents of one bag into another and waiting for a few minutes – all of which use exothermic chemical reactions. These meals can be used to motivate students to study such reactions relatively safely and without the use of a burner. Plus there is the

2. Objectives The objectives of this experiment are to observe the keeping quality of some food products‚ study the various simple methods of moisture determinations using different drying method. And determine the water activity in some food samples such as biscuits‚ bread‚ flour and instant noodles by using water activity measurement machine. 3. Theory To determine the moisture content in the food‚ methods such as open dish method and infrared balance method are used. 3.1 Hypothesis
