Which of these descriptions of units is FALSE? The partial pressure of a gas like CO2 in air divided by the total pressure of the air is the same as the concentration of the gas in the air. 40 Pa of CO2/100 kPa of air 400 micromol of CO2/ mol air Fun fact: 8 mm day of evapotranspiration is equivalent to 8L of water m ground area day. If you can work out why, then congratulations you are as nerdy...

Henry’s law states that the solubility of a gas is directly proportional to the partial pressure of the gas if the temperature is constant. Hyperbaric chambers, which provide high pressures (up to 6 atm) of either air or pure oxygen, are used to treat a variety of conditions, ranging from decompression sickness in deep-sea divers to carbon monoxide poisoning. Look up the Henry’s Law Constant (kH) for N2, O2, and CO2 in the textbook. a) Calculate the solubility (concentration in...

Find P air and V air ..
Water vapor accounts for part of the gas volume and S8 lle volum u sued must be corrected for the water vapor present. The vapor pressure of the water depends on temperature and the vapor pressure of water (PH,o) at different temperatures can be found in Table 1. If a Ph,o value at a particular temperature is not usted in the table, then it has to be found through the interpolation method from...

You are in charge of a combustion furnace. The furnace is fed an air stream and a methane stream which is combusted to produce heat that is used to boil water and produce steam for your plant. The combustion of fuels using an air stream which contains nitrogen generally produces significant amounts of NO, compounds which are an air pollutant, so the exhaust gases must generally be removed through various processes. In this case, your furnace exhaust is passed through...

Absorption and transmission: When a photon of light hits a molecule of gas or a particle in the atmosphere, there are three possibilities: 1) it can be absorbed (the energy is converted to heat), 2) it can be reflected (it continues on but in a different direction), 3) or it can be transmitted. These processes determine our ability to see distant objects (such as the mountains around Los Angeles and Irvine) and the colors in the sky (such as blue...

Which of the following statements is correct about the process of breathing in the MAMMALIAN Respiratory System? Strong contraction of the Diaphragm exerts a positive force on the Trachea and Bronchioles, which pushes air into the lungs through positive pressure. Breathing with Lungs must be more efficient than breathing with Gills, since atmospheric air has less oxygen available, when compared to the amount of oxygen dissolved in water. During Inhalation, contraction of the Rib Muscles and Diaphragm increases the volume...

Approximation At some point, scientists are confronted with the recognition that some math problems do not have exact answers. This is very different than the math we learn in high school and college, which typically represents math as a construction that only has exact answers (2 + 2 = 4 and not any other number) What is the expected time of diffusion of biologically important molecules at different scales? There is no exact answer to a question like how long...
