I need help with the following questions:
1. Why is it necessary to start this experiment with a large excess of ice in the metal ice container (the calorimeter)?
2. If all the ice melts when you were doing this experiment so at the end of the procedure you have a colorimeter full of water, how would this affect you result? Would you calculate a caloric value of your food to be higher or lower than true value?
The amount of energy that was harnessed in the nut and ultimately transferred into the melting of ice in the calorimeter is measurable based on how much water there was after the whole nut was burned. As a result, the amount of energy you can measure is directly related to how much water you collect, out of a total of however much ice there was at the beginning.
If there was too little ice, say, a single, small cube of ice, by the end of the burning we will have a puddle, but how do we ...
The expert determines why it is necessary to start a calorimeter experiment with a large excess of ice in the metal ice container.
