Nutritionists typically assign average values of 38 kJ/g (about 9 Cal/g) and 17 kJ/g (about 4 Cal/g) for fats and carbohydrates, respectively, although the actual values for specific foods vary because of differences in composition. Proteins, the third major source of calories in the diet, vary as well.

In humans, metabolism is typically measured in Calories per day. A nutritional calorie (Calorie) is the energy unit used to quantify the amount of energy derived from the metabolism of foods; one Calorie is equal to 1000 calories (1 kcal), the amount of energy needed to heat 1 kg of water by 1 °C.

A very brief introduction to Gibbs free energy and its relationship with equilibrium constants. large negative values of ΔG° have large values for their equilibrium constants, The key equation. ln K (that is a letter L, not a letter I) is the natural logarithm of the equilibrium constant K. For the purposes of A level chemistry (or.

The potential chemical energy of these molecules is transformed into other. the major energy value of certain foods in order to calculate the caloric values that.

Heat Capacity Formula. C. This is the 'specific heat' of the object (a defined physical/chemical property) multiplied by its mass and the change in temperature.

Jan 02, 2013  · First, let’s make sure everybody here understands what a calorie is. A calorie is just a measurement of energy- the amount of energy needed to raise 1 gram of water 1 degree Celsius at standard atmospheric pressure. This makes sense when talking about calories in food.
