Use this info to determine the Calories per gram (food calories) of a peanut: Peanut burned under 100 ml of H2O. Initial mass peanut = 2.1g Final mass peanut = 0.2g Initial temp H2O = 22 degrees C Final temp H2O = 48 degrees C Energy gained = (mass of water) x (change in temperature) x (specific heat of water) calories per gram = Energy gained ÷ change in mass. Note: The specific heat of water is 1 calorie ÷ (1 g x 1°C).

Alicia wants to find out how much weight a person will gain as a result of eating Halloween candy. She will use volunteers divided into 5 groups (large population, randomly assigned). Each group will eat an equal mass of a different candy. The first group (1) eats 4 kg of Hershey's chocolate. The second group (2) will eat 4 kg of candy corn. The third (3) will eat 4 kg of Skittles. The fourth (4) will eat 4 kg of Hot Tamales. And the 5th group (5) will eat no candy. Alicia will obtain average weight per person prior to the candy eating, and again 3 days after eating the candy. She will record the average amount of weight gain per person in each group. These group members will not be allowed to be active in any way, so that they will not accidentally lose weight. Alicia's data is in the table below...
