__1.) //How// did you determine what volume of air would be required?__
====We began by each person, one at a time, jogging in place while blowing into a beach ball. The person jogging in place would count how many breaths that it took to blow up the beach ball and another person used a stopwatch to time how long it took for them to blow it up all the way. We did this to determine the volume of air needed for 30 minutes of breathing. We used Boyle's law for the formula, and from there we found our pressure and volume. Through cross multiplication we figured out the volume each of us needs. ====

__2.)What volume of air did you determine would be required for a 30 minute dive? __
====Our average compressed air for 30 minutes is 4483.3cm^3. Breanna's was 6904cm^3, Sarah's was 3744cm^3, and Stephanie's was 2808cm^3. The volume of the beach ball was calculated to be 137.3cm^3, and the volume of 'our tank' was 80.1cm^3. We cross multiplied the volume of the beach ball to the volume of the tank and then we did the number of breaths for the beach over the volume of the beach ball. We plugged this into Boyle's law. P1was1atm and P2 was 2atm; volume1 was how many beach balls we could fill up in the tank. ====

===__3.) Use the appropriate gas law to make the calculation of final pressure that your sir will be under when it is in the tank. Which gas law will you use? __===

===__4.) The volume of air that you calculated for a 30 minute dive was the volume of air breathed on land. What volume of air would you need to compress for a 30 minute dive at a depth of 10 meters? __===

===__5.) Why might it be important to consider the temperature of the water where the dive would occur when doing the calculations for this experiment? Would the amount be different for diving off the coast of Maine in June compared to diving off the Florida keys in that same month? What would happen? __=== ====When it comes to temperature and pressure, they both affect each other significantly. As temperature increases, so does pressure, and when it gets colder, the pressure also decreases. While diving, if the temperature in the water changes, the pressure on our air also changes. This is why regulators are extremely important while deep-sea diving. If you were to dive off the coast of Maine in July, the temperature of the water would be much cooler than it would be in the Florida Keys. ====

__7.) Why are pressurized tanks required for deep sea dives? What can happen? __
====Pressurized tanks help keep the pressure inside the tank balanced which helps the diver to breath safely. As you descend below sea level, the pressure in the tank decreases rapidly. The regulator keeps these pressures balanced. ====

===__8.) What might happen if an over-filled scuba tank was left sitting in the sun on a hot day? Why? __=== ====When temperature increases, the pressure inside a tank increases. The tank would probably explode/bust because as the pressure on the air increases, the air has nowhere else to go. ====

===__9.) Use what you have learned about scuba diving to hypothesize what problems might be encountered in a suddenly depressurized airplane cabin at 30,000 feet. What would happen? Why would it happen? __=== ====The sudden drop in air pressure would probably cause the passengers in the cabin to faint/ pass out. The passenger's lungs and the airplane cabin wouldn't have enough time to adjust to the new air pressure, therefore their bodies would not have sufficient oxygen. ====
