Consider a box divided in half. One side is filled with 1 mol Ne at 300 Kelvin, and the other is filled with 1 mol Rn at 300 Kelvin. A small hole is opened in the divider between the sides, allowing the gases to mix. Suppose it takes 4.0 minutes for the Rn pressure to equilibrate between the two sides. How long (min) will it take the Ne pressure to equilibrate?
CPAP is the acronym for "Continuous Positive Airway Pressure". A CPAP device is used in respiratory therapy. Some ambulances carry a CPAP device. The pressure unit used in CPAP devices is "cm H2O". A typical pressure setting on a CPAP device may be 9 cm H2O. Blood pressure is commonly measured in units of mm Hg (or millimeters mercury). Which of the following statements is true regarding the pressure of 1 cm H2O ? Question 17 options: A) 1 in H2O has a lesser pressure than 1 cm H2O. B) 1 in H2O has a greater pressure than 1 cm H2O.
