The answer is B. <span>The individual trials and the averages should each have their own columns in the data table.
In an experiment, you want to be able to see all of the data, so you should always include the data from each individual trial; however, it's important to have a separate column for averages, so you are able to compare all of the data. Hope this helps! :)</span>
B. The individual trials and the averages should each have their own columns in the data table.
Explanation:
It is important to show all data clearly when conducting an experiment. So it is essential to have separate columns for individual data and another column for the averages of different data in different individual trials. This allows readers to compare the data obtained in individual trials with the calculated averages. This also provides a lucid way to observe the deviations made, if any.
Anytime energy transfers between 2 places or things some of it is 'wasted' as thermal energy (heat). This could be by friction or a change in temperature from a reaction. We say it is wasted because this heat energy serves no purpose.
