Food Calorimetry Lab: Calculations

To see all my Chemistry videos, check out
socratic.org/chemistry
How many calories are in a food sample? We can find out by burning a potato chip, causing it to release energy. This will be absorbed by water in a calorimeter, so we will then calculate how much energy the water absorbed, using an equation for heat energy, specific heat, mass, and change in temperature (delta temperature). We will also calculate the Calories per gram and Calories per serving, and then calculate percent error to find out how far off out experimental numbers were from the real values.

    What bugs me is how you can ever warm up 150g water by 65 degrees celcius by burning a single potato chip. Id have enough trouble getting it to burn at all. If youd start at a moderate temp of 35 deg, that water would be boiling! What kind of crisps are you using? Made of gun powder?

  • @hannahriedl3920

    How would I solve this, I am so confused...Using dodecane, the calorimeter constant was found to be 28.9 kJ/°C, calculate the amount of kilocalories (Cal) per gram given off by a unknown sample if burning 0.5 g caused the temperature of the calorimeter to rise from and initial temperature of 25.0 °C to 30.5 °C. (Reminder: food labels use calories (Cal); 1 Cal = 1000 cal; 1 cal = 4.184 J)
