The water test for Lake Hodges were rather shocking and scary. Most of the things that we tested for in the water had no signs. Half way through analyzing our data I almost came to the conclusion that we did some tests wrong. My partner luckily convinced me that our water just was just as bad as we thought. Communicating with the other teams on this issue resolved the rest. This was challenging as we spent time discussing to see if we needed to re do the tests which would have taken even more time. Another challenge were the gas laws problems. It was a difficult task at first. I understood how to do the first page as the formula set was surprisingly simple. It was the last two pages that threw me off, there was a lot of wording so my mind got wrapped around the words. In the end I believed that the problems were way more complicated than I thought. When I run into a situation that is similar in the future, I will not hesitate to go up to Ms. Lyman to ask about the meaning of the math problem. What it is asking me to find. In this situation my lab partner saved me from extra trouble. He explained how to do the other formulas and I soon realized that we already learned how to do everything on the sheet. The Gas Laws became a lot easier, besides from the few mess ups. I require myself to make less mistakes by taking more time to dissect the problem in what it is asking and the steps that are needed to solve the issue. I did a variety of water test on my Local Hot Tub. Those tests were Copper: In the ten minute test, there was no change to he water's color; No Copper. pH: A Yellow-Greenish color; pH 7. Chlorine: Plenty of it, it's a hot tub after all; Water turned yellow immediately. Chromium: Water stayed clear; No Chromium. Cyanide: Stayed clear; No Cyanide (Good thing) Nitrate: Immediately became Pink, end magenta; A lot of Nitrate. Silica: Became a dark blue; Silica is present. Phosphate: Immediately turned Light blue (Stage 3). A minute passed and it became Stage 4. Turbidity: 20 JTU (Jackson Turbidity Units) The amount of chlorine in the hot tub would kill any fish in the water almost immediately. The amount of nitrate and water makes a pollutant and would promote plant growth if there was no chlorine. Fish will not be able to live in a public hot tub. Our group did test for Lake Hodges located in Escondido. The test we did were as followed. Alkalinity: 80 ppm (barely below safe levels) Acidity (pH): Water became a Blue-Green color, has a pH of 9. Sulfide: Water stayed clear, no sulfide is present in water. Nitrate: Test turned water white, the water stayed white indicating that there was no Nitrate. Ammonia: Water stayed clear and did not turn yellow, no Ammonia was present. Cyanide: Water stayed clear, no Cyanide is present. (really good) Chromium: Water stayed clear, no Chromium is present. Iron: Water stayed clear, no iron (not good) Silica: Water turned a blue color, Silica is present. Copper: There was no change to the water's color after ten minutes. No copper is present. Having no Iron is bad for fish as all animals need a small amount of iron to survive. Plants overall don't do well without Nitrate. The amount of alkalinity is really good for the lake, but the pH of the water is 9 which is way too basic for any fish to survive in. It is remotely surprisingly that any plant life is in Lake Hodges. Lake Hodges needs more Iron less nitrate and a low pH level.
Gas Laws Math Problems: 1) On the planet Schöup. There is a citizen Soop boiling water at sea level at 210 Celsius While on Earth there is a scientist boiling water at sea level at 165 Celsius. The pressure on Earth at sea level is 100 kPA. What is the pressure difference at sea level between Schöup and Earth. 2) On one fine afternoon. Francesco and I were just having the most wonderful picnic. We both had water bottles by our sides. Francesco finished water bottle was crushed to the side of him with a mere 0.5 L of volume left. It is surprising that the bottle didn't burst. The cap was on in it's crushed state as well. "Hey Cole, I'm going to blow up the water bottle to see if I can get it to its original shape." Francesco was really well at expelling air out of his lungs at high velocity and proceeded to get the bottle back to its 1.2 L form. He also managed to get the pressure to 2.7 atm without letting any air leak out. What was the pressure that the bottle had in it's crushed state? 3) I went to the store to buy my good friend Orville some chips. The store was pretty cold at a good 60 F, same goes for my car. Poor Orville being an Elephant couldn't eat his sandwich. Elephants are just all feet aren't they, I couldn't imagine being asked to eat a sandwich with my feet. Orville's house is warmer than my car and the store. The initial volume of the bag was about 0.75 L or was it 1 L? No, it was definitely 0.75 L. It was looser than most bags. When I got into Orville's house the bag slowly inflate without my knowledge. When I gave him the chips the bag was at an incredible 1.2 L in volume. I wonder how hot his home was? How to solve: 1) P1/T1 = P2/T2
Step 1; Write everything you know out P1=First Pressure=100 T1=First Temperature=165 P2=Second Pressure=? T2=Second Temperature=210 Step 2: 100 kPa/165 C = x/210 C 0.61 = x/210 C 210 C * 0.61 = x 210 C * 0.61 = 128.1 kPa x = 128.1 kPa 100 kPa/165 C = 128.1 kPa/210C 2) V1 * P1 = V2 * P2 Step 1; Write the information you have V1=First Volume=0.5 L P1=First Pressure=? V2=Second Volume=1.2 L P2=Second Pressure=2.7 atm Step 2; 0.5 L * x = 1.2 L* 2.7 atm 0.5 * x = 3.24 (Reverse the problem to find x) 3.24 / 0.5 = x x = 6.48 atm 0.5 L x 6.48 atm = 1.2 L x 2.7 atm 3) T1/V1 = T2/V2 Step 1; Write everything you know T1=First Temperature=60 F V1=First Volume=0.75 L T2=Second Temperature=? V2=Second Volume=1.2 L Step 2; 60 F/0.75 L = x/1.2 L 80 F = x/1.2 L x = 1.2 L * 80 F x = 96 F 60 F/0.75 L = 96/1.2 L
