We were able to find the number of food calories by solving for "chemistry calories". By burning the food and letting the heat be absorbed by water, we could solver the equation q=mcΔt where q lost by food is equal to q gained by water. Here is our data below:
Questions:
1. We measured the temperature of the water.
2. We measured both the energy released by the food and gained by the water because they are equal and set the two equations equal.
3. The energy is absorbed by the can or the beaker. It is absorbed into its surroundings.
4. I was surprised that the individual foods had such small amounts of calories, and that the cheese puff has less calories than the pecan and cashew.
