UE/FALSE INSTRUCTIONS: Mark "A" for True and ..?" for False 1. Dalton's law states that A. gas volume and temperature are directly proportional. B. gas volume and pressure are inversely proportional. C. in a mixture of gases like air, the total pressure is the sum of the individual partial pressures of the gases in the mixture. D. the volume of gas that will dissolve in a solvent is proportional to the solubility of the gas and the gas pressure. E. None of the answers are correct. If the partial pressure of oxygen in both air and water is 100 mm Hg, then the concentration of the oxygen is the same in the air and water. A. True B. False Which of the following is the most accurate definition of external respiration? A. The process of CO2 production and O2 consumption during acrobic metabolism B. Bulk flow (convection) of air or water to and from the gas-exchange membrande C. The process by which CO2 is transported to the gas-exchange membrane from the environmental medium and O2 is transported away from the membrane into the environmental medium D. The process by which O2 is transported to the gas-exchange membrane from the environmental medium and CO2 is transported away from the membrane into the environmental medium E. Diffusion of O2 and CO2 across the gas exchange membrane C If the absorption coefficient of O, in seawater at 10°C is 0.5 mmo/L. What is the concentration of O2 in the water if the air O2 partial pressure is 0.21 atm? A. 3.0 mmol/L B. 1.5 mmol/L C. 0.5 mmolV/L D. 0.3 mmol/L E. 0.1 mmol/LExplanation / Answer
Ans 1 option c is correct.
Dalton's law expresses that the total pressure of gases is equivalent to the whole of the partial pressure of the part gases:
P TTotal =Pgas 1 + Pgas 2 + PPgas + ...Pgas n
Dalton's law can likewise be communicated utilizing the mole division of a gas,
P gas 1 =x1( P Total)
