    Please explain the relationship between calories, food, and heat by responding to the following prompts:

    1. List the 'magic formula' for weight loss. List a high-calorie food and a low calorie food. Do you see a relationship between the high calorie foods and the low calorie foods (other than the number of calories?)

    I can only think that less calories in and more calories burned, but am not able to take it a step beyond that in Chemistry terms.

    2. Explain why food has caloric values listed on the package. Relate food 'calories' to heat 'calories'.

    3. Water is often used as a heat sink because of its high specific heat. Explain what this means and give examples where this is used.

    4. There is a diet called the master cleanse diet where you only drink water with cayenne pepper and maple syrup in it for anywhere from 14-30 days. Why the cayenne and maple syrup (from a chemistry perspective) and isn't this considered starvation?

    1. List the 'magic formula' for weight loss. List a high-calorie food and a low calorie food. Do you see a relationship between the high calorie foods and the low calorie foods (other than the number of calories?)
    I can only think that less calories in and more calories burned, but am not able to take it a step beyond that in Chemistry terms.
    You're correct about taking in fewer calories than you burn for weight loss. Essentially, calories are a measure of energy, so in chemistry terms, you need to use more energy than you take in. A high calorie food would be cake and a low calorie food would be carrots. Higher calorie foods have more fat than lower calorie foods.
    2. Explain why food has caloric values listed on the package. Relate food 'calories' to heat 'calories'.
    Food has caloric values listed on the package so you know how much energy you are taking in when you eat it. A calorie is 4.184 J. A Calorie or kcal is 4,184 J. This is in terms of heat calories. Actual food calories are the same unit as kcal or Cal.
    3. Water is often used as a heat sink because of its high specific heat. Explain what this means and give examples where this is used.
    A high specific heat is just a way of saying that the substance can absorb a lot of heat without heating up quickly. Metal conducts heat well, so it has a low specific heat as it absorbs heat and its temperature increases quickly. Water has a high specific heat, so it can absorb a lot of energy without getting hot as quickly. This is used in engine coolant for cars. The heat from the engine is absorbed by the engine coolant (mostly water) so the engine doesn't overheat.
    4. There is a diet called the master cleanse diet where you only drink water with cayenne pepper and maple syrup in it for anywhere from 14-30 days. Why the cayenne and maple syrup (from a chemistry perspective) and isn't this considered starvation?
    Cayenne contains capsaicin, a chemical which helps speed up your metabolism, therefore burning more energy. The purpose of the maple syrup is to provide calories so you are not actually starving yourself. Maple syrup has a lot of calories because it is basically pure sugar. The cayenne pepper will boost your metabolism and the maple syrup will allow you to still intake calories your body needs to function.
