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.

When a driver brakes an automobile, the friction between the brake drams and the brake shoes converts the cars kinetic energy to thermal energy. If a 1 500-kg automobile traveling at 30 m/s comes to a halt, how much does the temperature rise in each of the four 8.0-kg iron brake drums? (The specific heat of iron is 448J/kg C.)
A large room in a house holds 975 kg of dry air at 30.0C. A woman opens a window briefly and a cool breeze brings in an additional 50.0 kg of dry air at 18.0C. At what temperature will the two air masses come into thermal equilibrium, assuming they form a closed system? (The specific heat of dry air is 1 006 J/kg C, although that value will cancel out of the calorimetry equation.)
Rubbing your hands together warms them by converting work into thermal energy. If a woman rubs her hands back and form for a total of 20 rubs, at a distance of 750 cm per rub, and with an average frictional force of 40.0 N, what is the temperature increase? The mass of tissues warmed is only 0.100 kg, mostly in the palms and fingers.
A large room in a house holds 975 kg of dry air at 30.0C. A woman opens a window briefly and a cool breeze brings in an additional 50.0 kg of dry air at 18.0C.

A pitcher throws a 0.142-kg baseball at 47.2 m/s. As it travels 16.8 m to home plate, the ball slows down to 42.5 m/s because of air resistance. Find the change in temperature of the air through which it passes. To find the greatest possible temperature change, you may make the following assumptions. Air has a molar specific heat of CP = 72IR and an equivalent molar mass of 28.9 g/mol. The process is so rapid that the cover of the baseball acts as thermal insulation and the temperature of the ball itself does not change. A change in temperature happens initially only for the air in a cylinder 16.8 m in length and 3.70 cm in radius. This air is initially at 20.0C.
The latent heat of vaporization for water at room temperature is 2 430 J/g. Consider one particular molecule at the surface of a glass of liquid water, moving upward with sufficiently high speed that it will be the next molecule to join the vapor. (a) Find its translational kinetic energy. (b) Find its speed. Now consider a thin gas made only of molecules like that one. (c) What is its temperature? (d) Why are you not burned by water evaporating from a vessel at room temperature?
One method at getting a tight fit, say of a metal peg in a hole in a metal block, is to manufacture the peg slightly larger than the hole. The peg is then inserted when at a different temperature than the block. Should the block he hotter or colder than the peg during insertion? Explain your answer.
The rate of heat conduction out of a window on a winter day is rapid enough to chill the air next to it To see just how rapidly the windows transfer heat by conduction, calculate the rate of conduction in watts through a 3.00-m2 window that is 0.634 cm thick (1/4 in.) if the temperatures of the inner and outer surfaces are 5.00 and 10.0 , respectively. (This rapid rate will not be maintained—the inner surface will cool, even to the point of frost formation.)
How can an object transfer heat if the object does not possess a discrete quantity of heat?
