Section 1 Map
Calculations: 55.4 − 32 × 59 = 13ºC + 273 = 283 K 35.6 − 32 × 59 = 3.6ºC + 273 = 275 K 27.3 − 32 × 59 =− 2.6ºC + 273 = 270.4 K 760 Torr × 1.00 atm = 1.00 atm 30.0 in ÷ .39370 = 76.3cmHg × 10 = 763.0mmHg × 760mmHg 760 Torr 760 Torr × 1.00 atm = 0.74 atm 22.1 in ÷ .39370 = 56.3cmHg × 10 = 563.0mmHg × 760mmHg 760 Torr 760 Torr × 1.00 atm = 0.71 atm 21.3 in ÷ .39370 = 54.1cmHg × 10 = 541.0mmHg × 760mmHg 760 Torr
Calculation Questions: 1. 3.43 × 70 = 240.1 miles on one tank of H 2 2. 3.43Kg ÷ .0899Kg/m3 = 38.15m3 × 1000L m3 = 38, 153.50 Liters of H 2

4. 38, 153.50 L/atm 101325 Pa × 14.7 PSI = 51.1 P SI 5. 352 KP a ×101.325 KPa 101325 Pa 6. It would take 2 hours and a minute approximately to reach Copper Mountain, not including the time to fill up at the gas station, or any other delays.
Section 2 1mole 1. 3430 grams × 2.016grams of H2 × 22.4 L of H2 1mole = 38100 liters
38,100 liters × 0.15$ 1 liter = 5715$ is the total to fill up the tank of the Mercedes Benz. 2. After filling up the tank 89 miles still lie ahead, The engine in the Mercedes Benz can get 70mpKg and the tank is 3.43 Kg therefore the Mercedes can go 240.1 miles on one tank of hydrogen gas. This means the trip can be made on only one tank of gas after filling up because the total trip mileage is 219 miles. 3.The limitations of Hydrogen cars include the problem of storing the car. Hydrogen gas likes to expand and heat up, therefore leaving it inside a car tank can be dangerous therefore it must be vented every few days effectively wasting your fuel. Hydrogen is also extremely flammable when it is condensed . Think back to the Hindenburg blimp used in the 1930’s that eventually burned down because its fuel was hydrogen gas. A driver of a hydrogen car will have to be extremely careful when using the car.

Section 3 ● As we make our trip up to copper mountain, we noticed that the air pressure is getting lower. The pressure lowers because there is less air above us. It is almost the opposite of being deep underwater. When you are that far down, there is even more pressure. We can tell because our ears start popping a little bit, and our snack bags are more inflated than we remember. ● Tire Pressure at Ponderosa: 35.0 P SI 35 = x ... 9310 = 263x ... x = 35.4 P SI ● Tire Pressure at Eisenhower Tunnel: 263 266 ●
35 = Tire Pressure at Copper Mountain: 263
x 267 ... 9345
= 263x ... x = 35.5 P SI
●
As we went up the mountain, the snack bags inflated. This happened because the snacks were most likely packaged in a place with a higher air pressure, so when they got to a lower pressure area, they tried to balance out, thus making the volume of the bag increase. ● Our ears pop because of the pressure change. The pressure in our middle and inner ear is equal at Ponderosa. However, when we go even higher in altitude, the pressure in our middle ear is lower than our inner. The higher pressure air has to escape, so it leaves through the eustachian tube, which makes a “popping” sound. ● I think that our ears would pop even a few miles from the school, since really any change in altitude/pressure could make our ears pop.
Section 4: It’s lunch Time! And the only logical thing to eat when you're in the mountains of Colorado is bison steak! It takes eight minutes to fully cook an inch thick bison steak. Butane has a molar mass of 0.058124 kilograms per mole and with one kilogram of butane we can cook for 17.2 minutes because for each mole of butane we can cook for one minute. 1kilogram ÷ 0.058124kg/mole = 17.204moles This means that we will use about .58124 kilograms of butane to heat up and fully cook our bison steak. We will need to use 10 moles of butane for this process. 0.058124 × 10moles = 0.58124 moles used
A Trip To Copper! By Justin Cygan, Gage VaNetta, Mack Millar Chemistry Lab 7Gas Laws Even if we try to cook another steak as soon as the previous is done, we will not be able to make another meal . it takes 8 minutes to cook a steak therefore it will take .464992 moles to cook a steak if our stove is already heated and after our previous meal we would only have .41876 moles remaining which is .046 moles short of having enough butane. 0.058124 × 8 = .464992 moles 1 − .58124 = .41876moles remaining
Section 5: Conclusion The comprehensive purpose for this lab was to make a day trip to copper mountain without pathetically breaking down on the side of I70. To make sure we don’t break down, and to make sure we have a skiing day that we will remember for the rest of our lives, we had to be sure to follow gas laws, and their various intricacies religiously. Using our knowledge of gases, helped us determine that we could make the trip to copper in only one tank of hydrogen gas.1 We also calculated the cost of the hydrogen needed for the trip, which came out to 5,715 dollars 2 , it might not be related to gas laws or as good for the environment, but a internal combustion car might have been a more economical choice. As we continued into the mountains our 75 pound bag of fruit snacks inflated because of a decrease in the pressure.3 We arrived in Copper, some how not full from our fruit snack feast. Lunch is next, and Bison Steak is the only logical option. The steak took eight minutes to cook4 , which is quite normal for the meat of a large grazing 1 2

Luckily the inch thick steak was enough to satisfy our adolescent hunger. The skiing was great, and we smiled as we left the mountains. Our hypothesis, that via our calculations we would be able to reach the mountains, eat well, enjoy our skiing, and return home safely was proven correct. Error Analysis: Sadly, experiments are not always done perfectly. In the first trial of the butane molar mass, the wrong lighter was massed, and coincidentally the remaining calculations were incorrect and imprecise.5 A second trial was done and the calculations this time were correct and the lighter’s mass was correct.6
5
The original mass of the 1st lighter before collection was 15.34, and after collection 15.07.
6
The second lighter’s mass, the correct one, was 15.77 before collection, 15.64 after collection.
