The following data have been taken from the budget reports of Brandon company a. Beakers have wide mouths and flasks do not. Two containers are connected by a stopcock as shown on the right. What will the resultant pressure be when the stopcock is opened?
If we increased the number of atoms, we would see that the probability of finding all of the atoms in the original flask would decrease dramatically following (1/2) n, where n is the number of atoms. Can you help me with this AP Chemistry gas laws problem? An 60 litre metal vessel contains carbon dioxide at 160 kPa and 23oC. The likelihood of all atoms being found in their original flask, in this case, is only 1 in 4. The stop cock is opened to allow the two gases to. 8 L and contains hydrogen gas at a pressure of 1. Two-Atom, Double-Flask Diagram. Question: Natural gas is a mixture of hydrocarbons, primarily methane () and ethane (). 14 Two Flasks Are Connected With A Stopcock Flask 1 Has A Volume Of 25 L And - ENGINEERIN101 | Course Hero. Assuming complete combustion of both gases in the natural gas sample, what is the total mass of water formed? Become a member and unlock all Study Answers. Qualitative Estimates of Entropy Change. Upload your study docs or become a. For Ar gas: The partial pressure of Ar is calculated as. 38 x 10-23 J/K), and W is the number of microstates.
Microstates are the number of different possible arrangements of molecular position and kinetic energy at a particular thermodynamic state. Rearrange the above expression to the final pressure. These definitions can seem a bit vague or unclear when you are first learning thermodynamics, but we will try to clear this up in the following subsections. The second law of thermodynamics states that a spontaneous process will increase the entropy of the universe. Our experts can answer your tough homework and study a question Ask a question.
2 mL at a temperature of and a pressure of 734 torr. Last updated: 7/9/2022. 8. sin α 08 O 2 O 1 D 1600 R 1 R 2 W A h 2 h 1 O 2 O 1 D R 2 α 3 kN 1 kN B R 3 R. 384. To be able to estimate change in entropy qualitatively. 00 atm at 25oC, it is found to have a volume of 1.
I know it's easy, but I don't know which formula to use.
Some claim that beating the steel realigns the grain of the steel better or that they are "packing the edge". You can't beat goodness into steel. Overall knife measurements may vary some due to the nature of hand forging material. The original Bowie knife was actually designed and commissioned to be made by James Bowie's older brother Rezin Bowie and given to James so that he would never again be caught unarmed. It's solid, heavy, and well balanced. How to Make a Railroad Spike Knife? : 7 Steps (with Pictures. Damascus gets it's name from the region where it is believed to have originated, Damascus Syria. There's something organic about making this strong item from an old Spike. How to Forge Spike Knife from a Railroad Spike? We only use new, high caliber railroad spikes and our quality and consistency is 100% guaranteed. Nobody really knows for sure what the original Bowie knife looked like but it is pretty certain that what has become known as the Bowie knife today bears little resemblance to the original.
Each maker would have imparted his own style and interpretation to the knife and perhaps Rezin even refined the design himself. Railroad spikes are readily available, usually for free, they are a novel item, and they can make a perfectly useable knife. Any good metallurgist will tell you that it's all nonsense. "I would be afraid to use it and scratch it up". This hand forged fist blade is fully functional, so if you choose to use it for self-defense or survival you're well-equipped. I prefer modern stainless steel alloys for most of my my knives. I use Cliff's example because this happens to be one of the most used and carefully documented mirror polished 440C knives I know of. The resulting steel is then acid etched to show the layers as the acid (usually something like ferric chloride) attacks the different types of steel in different ways. I made this for a friend that works for the Alaska Railroad. The more carbon content, the harder the steel, up to a point anyway. Knives made from railroad spike jonze. Once the shape of the spike is created, further shaping and blade sharpening continue by using the grinder. Address your package to Once in a Blue Moose, take it to your local post office, and pay to return your order: Our return address is: Once in a Blue Moose 1041 W. 25thAvenue Anchorage, AK 99503.
It has not been re-polished since it was made in 2005. Instructor: Bill Weinert. I've made three large knives now from single railroad spikes (I pound out the entire spike, head and all, to get the most metal out of them). Railroad spike knife designs. Old automotive springs, plow shares, saw blades and old files are commonly used to forge a knife blade. Blacksmithing can be done from home if you have the right setup and tools. Railroad spikes are a medium carbon steel and will hold an edge but not be a high performance skinning knife. After grinding, the steel is acid etched to bring out the unique patterns of the many layers of steel. The sheath is double-stitched but I can't tell by feeling what material the stitching is. The loop on the sheath will easily handle a 2 and 3/4 inch belt.
Even though Bowie had been shot twice and stabbed several times, he recovered and went on to a number of ventures before dying along with 187 other defenders during the fall of the Alamo in San Antonio, Texas on March 6, 1836. Too much carbon content will make the steel too brittle for use as a blade steel. They reloaded and fired again. Excellent, or bad, knives can be made either way. It does take a lot of knowledge and experience to forge good Damascus. Railroad Spike Alaska Knife. Twist the Handle for Beauty. Various types of patterns can be created in the steel by using special dies when forging it or by twisting the billets.
Some layers will turn darker than others when acid etched so the pattern shows up. Solid as they come, you can really drive this knife through just about anything by hitting the spike end which was made to take a belting. 8 ounces of solid metal that erases all doubt you may have had about this novelty knife being a functional weapon.
