In normal breath, about 0.5 L of air at 1.0 atm and 293 K is inhaled. About 25% of the oxygen in air is absorbed by the lungs and passes into the bloodstream. for a respiration rate of 18 breaths per minute, how many moles of oxygen per minute are absorbed by the body? Assume the mole fraction of ocygen in air is 0.21.
How much energy (in calories) is needed to heat 12cm^3 of fat from room temperature (25C ) to its melting point (35C)? Specific heat of fat 0.45 cal/(g*C, and the density of fat is .94g/cm^3)
Consider 4.40L of a gas at 365mmHg and 20degrees C . If the container is compressed to 2.60L and the temperature is increased to 30 degrees C , what is the new pressure, P2, inside the container? Assume no change in the amount of gas inside the cy..
