1 If a 69 kg person ate 165 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. Enter your answer in ºC with at least 2 sig figs. Just so you are not afraid to eat or drink things, a healthy body is very good at regulating temperature- the bad news is that unless you use it right away, our bodies are very good at converting sugar into fat.
