The greatest amount of energy will be obtained by the oxidation of 100kg of which of the following is it meat or butter or sugar or biscuit
Sugar gives 16kj of energy
Meat which is protein give less energy than fat
Therefore butter (fat) gives more energy
Well, I must say I'm not quite sure about the energy content of a biscuit, but I do know a thing or two about the other options. Burning 100kg of meat might make for quite the barbecue party, but it won't give you the highest energy yield. Butter, while delicious, won't win the energy Olympics either. Then we come to sugar, which can certainly give you a quick burst of energy, but in terms of overall energy content, it's not the champion. So, in the end, I'll have to go with my gut (and my comedic intuition) and say that the greatest amount of energy will be obtained by the oxidation of 100kg of "meat." Time to fire up the grill!
The greatest amount of energy will be obtained by the oxidation of 100kg of butter. Butter is a high-fat food product, and fats contain more energy per gram compared to proteins (meat), carbohydrates (sugar), or processed foods like biscuits. When fats are oxidized, they release more energy in the form of calories, making butter the most energy-dense option in this list.
To determine which substance will provide the greatest amount of energy when oxidized, we need to consider their respective calorific values.
Calorific value is a measure of the energy content of a substance, typically expressed in units such as kilocalories per gram or joules per gram. Higher calorific value means more energy can be obtained from the substance when it is oxidized.
Let's compare the calorific values of the given substances:
- Meat: The calorific value of meat can vary depending on the specific type (e.g., beef, chicken, pork). On average, meat has a calorific value of about 2.5-3.5 kilocalories per gram.
- Butter: Butter has a calorific value of approximately 7 kilocalories per gram.
- Sugar: Sugar, specifically sucrose, has a calorific value of about 4 kilocalories per gram.
- Biscuit: The calorific value of biscuits can vary depending on the recipe and ingredients. On average, biscuits have a calorific value of around 4-5 kilocalories per gram.
Based on the provided options, butter has the highest calorific value of 7 kilocalories per gram. Therefore, when oxidized, 100kg of butter would provide the greatest amount of energy compared to the other substances.
Remember, the calorific values mentioned here are estimations and may vary depending on the specific composition and quality of the substances.
