Vedclass · Answer

(A) The energy requirements of animals and the energy content of food are expressed in terms of measure of heat energy because heat is the ultimate form of all energies. This is often measured to as calorie $(cal)$ or joule $(J)$. Since this amount of energy is always small, it is common to express it in terms of kilocalorie $(kcal)$ or kilo joule $(kJ)$. One kilocalorie is the amount of heat energy required to raise the temperature of $1 	ext{ kg}$ of water by $1^{\circ}C$. A normal human requires approximately $2500 	ext{ kcal}$ per day to maintain metabolic activities and physical work.

What is the average daily caloric requirement for a normal human (in $\text{ kcal}$)?
