If the partial pressure of oxygen drops below 110 mmHg , passengers become drowsy. If this happens, oxygen masks are released. What is the total cabin pressure at which oxygen masks are dropped? Express answer using two significant figures. So I thought this would be 650 mmHg - 30 mmHg (I got the 30 mmHg from 140 mmHg - 110 mmHg)...but the answer of 620 mmHg was marked incorrect (I also tried 6.2 * 10^2 mmHg, in case it was a significant figure issue, but that didn't work either). Thanks!arrow_forwardPractice Exercise 1If you fill your car tire to a pressure of 32 psi (pounds persquare inch) on a hot summer day when the temperature is35 °C 195 °F2, what is the pressure (in psi) on a cold winterday when the temperature is -15 °C 15 °F2?

- EXERCISE 1: A quantity of gas occupies a volume of 80 cm3 at a pressure of 750 mm Hg. What volume will it occupy at a pressure of 1.2 atm if the temperature does not change?arrow_forwardGas exercise: What volume does a gas occupy at 980 mmHg, if the container finally has a pressure of 1.8 atm and the gas is compressed to 860 cc?arrow_forwardExperiment 1. Observe the impact of temperature on gases in the scenario where the volume of the container can change.1. Place some dish soap on a small plate and dip the opening of the plastic bottle in the soap in order to form a film across the bottle opening.2. Squeeze the bottle slightly and observe the movement of the film. The pressure inside and outside the bottle is the same. Therefore, when you reduce the volume by squeezing, the air particles collide with the film and increase the volume (back to its original volume)3. Verify that the soap film is still present. If not, dip the bottle in the soap, so you have a soap film.4. Place hot water in a bowl and then hold the bottle in the water (only the bottom part needs to be in contact with the hot water). Observe what happens to the soap film.5. In your words, write down a molecular level description that explains what you just observed.arrow_forward
