Thus, if you are not sure content located 1000 mL of a gas is cooled from 500 K to 250 K. What is its final volume? As the bubbles rise, the pressure decreases, so their volume increases as suggested by Boyle’s law. While resting, the average 70-kg human male consumes 14 L of pure O2 per hour at 25 °C and 100 kPa. St. Louis, MO 63105. link to the specific question (not just the name of the question) that contains the content and a description of The total pressure of the gas mixture is 5 atmospheres.
