A chemist performs a calorimetry experiment on a peanut with a mass of 0.756 g. The calorimeter contains 1150 g of water at 25oC. If the temperature of the water increases to 27oC, what is the energy content of the peanut? = 9614 J . Hint: solve for the water and remember that the heat gained by water = heat lost by peanut

If the peanut falls off the pin, start over immediately. As soon as the peanut stops burning, immediately. take a final water temperature reading and record it in the data table. As soon as the peanut has cooled, use forceps to lift the burned remains onto the balance scale. Take a final peanut …

How Much Energy in a Peanut - Energy in our Lives
Apparatus for determination of the energy of a peanut. 5. CALCULATIONS: In this experiment, heat is measured in joules. 4.18 joules is the quantity of heat needed. to raise the temperature of one gram of water by 1ºC. Due to the excess of ice in the metal can, the temperature of the system should remain constant at 0ºC, thus we are melting ...

By burning pieces of food, the chemical energy stored in molecular bonds is released as heat and light. The heat can be measured in units called . calories. A calorie is the amount of heat (energy) required to increase the temperature of one gram of water by one degree C. This process is the basis of the technique of . calorimetry.
