- Q: Density of copper is 8.92×10^3 kgm-3mass of 1 mole of copper is 6.35×10^-2kg
- copper adopts a face-centered cubic arrangement in its crystal lattice. What this means is that the diagonal from one corner of a phase of the unit cell to the opposite corner of the same phase is equivalent to 4r and also equals (2^1/2)a; therefore, r = [(2^1/2)/4]a = a/(2(2^1/2)) Since the edge of the unit cell equals a, the separation between two copper atoms on the edge of the unit cell is: Hole = a - 2a/(2(2^1/2) = a[1 - (2^1/2)/2] = 0.293a I hope that answers your question.
- Q: I know they stopped in 1982, but when did they start?Also for a bonus if you know when they started and stopped making Canadian pennies out of copper as well.
- The first year for the 95% copper cent was 1864. The only year between 1864 and 1982 where it wasn't copper was 1943, when it was made out of steel (the copper was considered a vital war material). From 1857 through early 1864, the cent was made out of 88% copper and 12% nickel. Before that, it was essentially pure copper (there were often impurities, depending on where they got it from). For Canadian cents, the last year for the bronze cents was 1996
- Q: 1. Will aged copper tube affects manufacturability i.e. bending, expansion, etc 2. Will aged copper tube causes the change of material properties i.e. elasticity, yield strength, elongation, hardness, etc.?3. What’s the maximum storage time (under shelter, ambient temperature and humidity) for copper tube before resulting problem indicated above (no. 1 and no. 2)?4. What’s the problem on aged copper tube other than problems indicated above (no. 2)?5. What process can cure/heal aged copper tube in order to prevent problem indicated above (no. 2)?Please provide the source of your answer (literature, journal, books, etc)Thank you.
- Copper doesn't age. It will develop a coating of green patina, which is just copper oxide. But this is thin, and doesn't effect any of the properties of the copper. If you want to get rid of the patina, just rub it with some emery cloth. It's only a thin surface layer. .
- Q: What will happen to the air conditioner after installing 16 and 10 PCT?
- Well, the problem came out, we know that the liquid is compressed. When the liquid refrigerant from the suction port into the low-pressure compressor, will produce a "liquid hammer" phenomenon of compressor, this phenomenon is very serious damage to the compressor. This is a major problem, such as the rest will change the flow, increase the compressor noise and expansion valve and so on a series of problems.
- Q: So I have some copper I want to scrap but when I called the yard to get prices they said there is two types and they are running $1.10 and $1.00. How would I tell the difference between the two and would I have to separate them before bringing them in?
- This has nothing to do with chemistry or mineralogy, it most likely is to do with the NATURE of the copper being brought in. It may be that plate copper or plumbers' copper pipe trades at the higher price and copper wire trades at the lower price. It maybe that the lower price relates to copper wiring that hasn't had the plastic coating removed. Ask them to be specific; what copper items do you pay $1.10 /lb for and what items do you pay $1.00 / lb for?
- Q: a copper pipe to my garage split over winter but I can t fit a sleeve over top to sweat it to my other pipe which connects to the spigot. I cut out where it split. the outside diameter of the swollen pipe is 17mm, whereas the inside of a joining sleeve is only 15.5mm - any way to stretch a sleeve without fancy tools? Grinding things down didn t seem to work.
- over at the home improvement store, you look for a non metallic sleeve that clamps onto both sides. Tell the assistant in plumbing what you're trying to do. This solution is NOT for potable [drinking] water, only for washing/gardening water. The better solution is to replace all of the expanded pipe -- what happened is water inside the pipe froze and enlarged the pipe -- this inherently makes it brittle and subject to leaking at every join [plus in the middle]. When you do this replacement, be sure to include a shutoff at the edge of the warmed area [preferably inside the warm area but we can't always get what we want] and drain. This line needs to be turned off and drained to prepare for future winters.
- Q: What is copper used for in technology? or what is it's uses in technology?
- copper is used most extensively for all the wireings in each and every electrical item u see all motors have copper its there in electromagnets u name it it has copper copper utensils are also used in many places it has like infinite uses
- Q: Is the brass tube of the GREE air conditioner the same? Reward points: 0 - 14 days from the end of the problem, 23 hours ago, bought a GREE, GREE, KFR-26GW/K (26556) B1-N1, and later found that refrigeration is not enough. Change the big one for the boss. It's GREE KFR-35GW/K (35556) B1-N1. At the time of loading. May be installed staff feel that it is troublesome to change copper tubes again, using the original KFR-26GW/K (26556) B1-N1 copper tube. I asked if the copper tubes were the same. He said it was the same. Look, I don't believe it. He pointed to the outer packing box. I saw the standard they wrote was the same. Also said that the copper pipe can be connected, and if the model is different, you can not connect. I'm still a little doubt that GREE KFR-35GW/K (35556) B1-N1 and KFR-26GW/K (26556) B1-N1 brass is not the same, is not the air conditioning copper are the same, but their refrigeration is not the same as the number of horses, one is a horse, a horse is 1.5, all with the same brass???
- As long as the nut is screwed, it can be used,
- Q: do you braze it ?
- You need to sweat the pipe. First clean the pipe with sand paper on both ends until they are shiny. Apply flux to both ends of the pipe and inside the female ends of the gate valve. Protect any flamable exposed materials near the joint. Heat the pipe at the connection joint with the valve with a propane torch until the solder will melt when you touch it to the connection joint. The flux acts as a sponge to draw the solder into the joint. 3 is a big pipe so be sure that the solder has gone in all the way around the pipe. Good luck.
