Do not stay in the laboratory burning peanut and position it so that the top of the flame just touches the bottom of the can allow the peanut to burn completely if the flame goes out how does your value for the caloric energy of a peanut (or other food) compare to the label information.
Lab, however, you will actually light the peanut on fire and burn the peanut so that the hydrocarbons in the carbs and fats undergo combustion the heat from the peanut will be absorbed by the water in a calorimeter.
Purpose: the purpose of this lab is to measure the amount of calories in one peanut hypothesis: if the heat of the peanut burning raises the temperature of the water, then we will be able to calculate the amount of calories in a peanut procedure: we first created a calorimeter for the lab we measured the weight of the aluminum can with 100ml of water.
Lab answers: energy from burning hypothesis if the change in temperature is greater when the water is heated with the use of the fire caught by the food substance, then the energy content in the food substance is higher because the heat energy is greater, since the heat energy is absorbed by the water when the fire is kept under the test.
In this laboratory, students burn a peanut, and use the heat that it gives off to heat a can of water thus, they learn about the energy content of food and about energy transfer processes.
Burning peanuts to simulate cellular respiration this lab will be assessed on conclusion & evaluation aim to determine the average energy content of 1g of peanut. Burn a peanut count calories burn a peanut and use the heat to boil water introduction a peanut will burn producing an impressive amount of flame for a long time. Peanut calorimetry lab procedure 1 weight the shelled peanut and record in grams 2 place peanut on the peanut stand 5 hold test tube with test tube holders over the peanut and light peanut 6 while the peanut is burning, note the rise in temperature and record the final highest temp of water when peanut is finished burning set-up.
