“Calorie” is a _______.

“Calorie” is a _______.

  • (A) Unit of diet
  • (B) Unit of quantity of heat
  • (C) Unit of food intake
  • (D) All of these
  • The correct answer is (B) Unit of quantity of heat.
  • A calorie is defined as a unit of heat (energy), although it is often used as a measure of food energy in dietetics.
  • Let’s analyze it carefully all options:
  • (A) Unit of diet → Not entirely correct. Although we discuss “calories in a diet,” the calorie itself is not a unit of diet but a measure of energy.
  • (B) Unit of quantity of heat → Correct answer. By definition, 1 calorie is the amount of heat required to raise 1 gram of water by 1°C.
  • (C) Unit of food intake → Misleading. Calories are a measure of the energy in food, not the quantity of food.
  • Thus, (D) All of these is incorrect because only option B is scientifically correct.
