Question

If a 59.04 kg person ate 232 calories worth of sugar (about the calories in a typical energy drink and they converted all of that energy to heat immediately, what would be the change in temperature of that person?

A couple of useful facts for this problem.

Food calories are actually kilocalories.
1.000 kilocalorie = 4184 Joule
We will assume that the average specific heat of this person's body is 3.00 J/gºC.

Expert Solution

Step 1

Given that amount of kilocalories consumed is 232 . It can be converted into Joules as shown below:

$\begin{array}{rcl} 1.000 kcal & = & 4184 J \\ 232 kcal & = & \frac{4184 J \times 232 kcal}{1 kcal} \\ = & 970688 J \end{array}$
