- 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.arrow_forwardWe are doing an experiment on measuring the temperature. We are to measure the temperature of hot water (measure it initially, then wait for 10 minutes then measure again). Additionally, we are to measure the temperature of another water before and after putting ice (measure initially then measure 3 times [every 5 minutes] for 15 minutes). My question are: What law or principles of chemistry could be applied in this experiment? Should we expect the temperature of the hot water to drop? why? Should we expect the temperature of the water to rise or drop after putting the ice? why?arrow_forwardA 325.7 gram sample of copper is initially at 20.8 °C, and it absorbs 17.88 kJ of heat from its surroundings.
