RIGHT ANSWERS ARE GIVEN PROCESS TO THE ANSWERS ARE NEEDED. Bioenergetics is the application of mass and energy balances to living things. Consider the steady$-$state material balance on a person given in Table $1$ below.

a$)$ Calculate the rate of chemical energy obtained from the combustion of food in kcal$/$day using the mass flow rates given in Table $1$ and the energy available per gram of food in Table $2.$

Total energy from food: $2611\mathrm{.}1$kca$\frac{l}{d}ay$

b$)$ This chemical energy goes to:

vaporize water $($respiration and perspiration$)$;

heat loss to surroundings by radiation, conduction, and convection;

work done on the surroundings.
