How much energy is in a nut? Burn it and find out.The heat from the flame is energy released when carbon andhydrogen in the nut combine with oxygen in the air (oxidationreactions) to produce CO2 and H2O. Pierce a nut (pecanor walnut halves work best) with a bent paper clip that holdsthe nut above the table surface. Above this, secure a can ofwater so that you can measure its temperature change whenthe nut burns. Use about 103 cm (10 mL) of water and aCelsius thermometer. As soon as you ignite the nut with amatch, place the can of water above it and record the increasein water temperature once the flame burns out. The number of calories released by the burning nut can be calculated bythe formula Q = cmT, where c is its specific heat capacity(1 cal/g # C), m is the mass of water, and T is the change intemperature. The energy in food is expressed in terms of theCalorie, which is 1000 of the calories youll measure. So tofind the number of Calories, divide your result by 1000. (SeeThink and Solve 36.)
