When a PERCENT (%) is given in a problem, it means _______________
… parts per 100 parts.
It expresses the numerical relationship of the parts of a particular unit to 100 parts of the whole.

18 kg of body fat = 100 kg of body mass
UNITS OF ENERGY:
SPECIFIC HEAT (SH) * definition
Specific Heat (SH) is the amount of heat needed to raise the temperature of exactly 1g of a substance by exactly 1 degree C.
This temperature change is written as ∆T, where the delta symbol means “a change in”.
SH= heat/grams x ∆T = J (or cal)/ 1g x 1 ^oC
How to write calculations:
Heat = mass x ∆T x SH
ENERGY AND NUTRITION:
1 Cal = 1 kcal = 1000 cal
1 Cal = 4.184 kJ = 4184 J
Carbohydrates- 17 kJ/g; 4 kcal/g
Proteins- 17 kJ/g; 4 kcal/g
Fats- 38 kJ/g; 9 kcal/g
