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.

Ex: 18% body fat by mass

18 kg of body fat = 100 kg of body mass

UNITS OF ENERGY:

SPECIFIC HEAT (SH) * definition

- how it is written
- how to write calculations using SH

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

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
