Question:The vapor pressure of water at 40.0潞C is 7.34脳103 N/m2. Using the ideal gas law, calculate the density of water vapor in g/m3 that creates a partial pressure equal to this vapor pressure. The result should be the same as the saturation vapor density at that temperature (51.1 g/m3).
A high-pressure gas cylinder contains 50.0 L of toxic gas at a pressure of 1.40 x 107 N/m2 and a temperature of . Its valve leaks after the cylinder is dropped. The cylinder is cooled to dry ice temperature () to reduce the leak rate and pressure so that it can be safely repaired. (a) What is the final pressure in the tank, assuming a negligible amount of gas leaks while being cooled and that there is no phase change? (b) What is the final pressure if one-tenth of the gas escapes? (c) To what temperature must the tank be cooled to reduce the pressure to 1.0 atm (assuming the gas does not change phase and that there is no leakage during cooling)? (d) Does cooling the tank appear to be a practical solution?
Question:A deep-sea diver should breathe a gas mixture that has the same oxygen partial pressure as at sea level, where dry air contains 20.9% oxygen and has a total pressure of 1.01脳105 N/m2. (a) What is the partial pressure of oxygen at sea level? (b) If the diver breathes a gas mixture at a pressure of 2.00脳106 N/m2, what percent oxygen should it be to have the same oxygen partial pressure as at sea level?
At a spot in the high Andes, water boils at 80.0潞C, greatly reducing the cooking speed of potatoes, for example. What is atmospheric pressure at this location?
Question:Late on an autumn day, the relative humidity is 45.0% and the temperature is 20.0掳C. What will the relative humidity be that evening when the temperature has dropped to 10.0掳C, assuming constant water vapor density?
