yes it chemical energy
Photosynthesis is the conversion of light into energy. Digestion is the conversion of food into energy.
Water content of a product can be defined as the percentage weight of water in relation to the dry weight of the product.Water in food which is not bound to food molecules can support the growth of bacteria, yeasts and molds (fungi).
It could be either; but when you are talking about food, what is of interest is usually the energy content - meaning, chemical energy stored in the food. Heat IS energy, and a kilocalorie is the energy required to heat one kilogram of water by one degree Celsius.
That means how much energy it has.
calories
It is essentially chemical energy, which is released when the food is digested in the stomach
You burn it.
No, it list the energy content in calories, which is the amount of energy to raise a quantity of water by a certain temperature.
Any unit of energy can be used to describe the energy content of food.
AZU
Fats and oils are the foods highest in energy content.
Fatty and sugary foodstuffs have the highest energy content per weight unit.
A calorimeter. Basically you burn food inside a box and then measure the energy you get out of it. You have to make sure that the energy does not get out of the box
