The students burned peanuts and cashews in lab today to determine their heat
content, in Calories per gram. This is a cashew burning under an aluminum can
filled with water. The students measured the temperature change in the water,
the masses of nut and water, and calculated their answers. Some of the nuts
heated the 200 ml of water up to 70°C or more! This cashew was the best
fire I saw all night. The nut is mounted on a paper clip, about 1 inch above
the rubber stopper, and a half-inch or so beneath the can. The average heat
content for each nut was about 4 Cal/g.
