Human Metabolism

Being described as the most complicated machine ever encountered by humans, the human body and the cell metabolism is nothing less than a wonder. Metabolism is the set of life-sustaining chemical reactions within organisms.

Question

35. when we are hot, our body automatically increases the rate of perspiration. This
helps our body to cool down, mainly because:
(a) The more liquid (water) we loose, the less mass remains in the body, and
therefore total internal energy of the body decreases.
(b) The sweat evaporates, and it takes the heat of evaporation from our body.
(c) The relative humidity in the vicinity of our body increases, causing the skin to
"feel" colder even though temperature has not decreased.
(d) Sweat is hot, therefore as body losses it, we feel colder.

1.- In a laboratory experiment, a calorimeter is used to determine the specific heat of iron. 80 g of dry iron pellets are placed in the cup and heated to 95°C. The mass of the inner aluminum cup with a stirrer made of the same material is 60 g. The calorimeter is partially filled with 150 g of water at 18°C.The hot pellets quickly expired in the cup and the calorimeter was sealed, as shown in Figure 17.5. After the system has reached thermal equilibrium, the final temperature is 22°C. Calculate the specific heat of iron HEAT SPECIFIC Iron: 470 J/kgC: 0.113 cal/gCAluminum: 920 J/kgC: 0.22 cal/gC
