You are running a calorimetry experiment where you are trying to determine the number of Calories (with a capital C!) in a peanut. You set up your aluminum can of water and take all your initial data, putting it in the table below. Then, you set your peanut ON FIRE You finish filling out your table once the peanut has gone out. How many Calories of heat did your peanut release? Round your answer to two digits after the decimal point.

Initial Mass of Peanut 3.11 grams
Final Mass of Peanut 0.52 grams
Mass of Water 55.2 grams
Initial Temp of Water 23.2 degrees C
Final Temp of Water 71.3 degrees C

The number of calories of heat released by the peanut is

Explanation:

  Now from the data given we can evaluate the mass of the peanut that is burnt as

Substituting values

Generally the heat gained by the water can be mathematically represented as

Where is the mass of water which is given as

            is the specific heat of water which has a constant value of  

    Now is is the change in temperature which can be evaluated as follows

 Now

space exploration has led to the development and technological improvement of many everyday items. (if this answer is wrong i will find the right answer) : )
