- 3. What is the volume of a balloon that contains 4.00 moles of gas at a temperature of 127 °C and a pressure of 64 atmospheres? (Ideal Gas Law) 4. If a deep-sea diver has 0.050 Liters of gas in his blood under a pressure of 250.0 atm, then rises quickly to a depth where his blood has a pressure of 10.0 atm, what will the volume of gas in his blood be? (Boyles Law)A cell doesn’t need a circulatory system, but your body does. Let’s do a quick calculation to see why. A typical cell has a diameter of 10 mm. The smallest mammals in the world, shrews, are about 10 μm across. Compute the diffusion time for oxygen molecules through water at 25°C for these two distances.A molecule of oxygen has a speed of 473 m/s at a certain temperature. Determine the speed of the molecule in kilometers per hour km/ h

- What is true about the relationship between pressure and volume of a gas? The volume of a gas is always double the pressure. The volume of a gas is directly proportional to the pressure. The volume of a gas is inversely proportional to the pressure. The volume of a gas does not change when the pressure increases. ©2021 Illuminate Education TM, Inc. 田A runner weighs 663 N and 71% of this weight is water. (a) How many moles of water are in the runner's body? (b) How many water molecules (H2O) are there?A container holds 0.420 m3 of oxygen at an absolute pressure of 3.80 atm. A valve is opened, allowing the gas to drive a piston, increasing the volume of the gas until the pressure drops to 1.40 atm.
