Q:I was able to take a section that I soldered and wiggle the pipe until it became undone. Isnt a properly solderered pipe supposed to be pretty sturdy ay the joint?: You move the heat across the joint while touching the joint with solder. Then you will know when the pipe is at a temperature to allow the solder to run. then remove the heat, and apply solder around the joint and it will run into the joint. When you clean the pipe before soldering, do not touch the cleaned area until you have applied flux. To test the pipework, turn the water back on slowly, and check for leaks. if it seems okay, then turn the water on more, and check again.

Q:my science teacher said ions are created by filling the energy levels in the electron cloud and according to him to fill the fourth energy level of copper you need to add 7 electrons or lose 11 electrons he says there can be 2 electrons in the first level, 8 in the second, 8 in the third, and 18 in the fourth: Coppers ions are both those because it allows coppers ground state electronic configuration to adapt to whatever it wishes to bond to to make it a more stable atom.

Q:what do u think?How can two oscars of different colours, both be tiger oscars?* i have an oscar which is copper and tiger mix breed, so whats the speciality of copper and tiger both that makes them unique *and how to recognise a copper oscar and tiger oscar?and why are copper oscar oscars more costly...?thanx!!.: One okorder

Q:While trying to remove the water supply shut-off valve to the toilet, the copper pipe from the wall began to rotate. I was worried I may have damaged the pipes behind the wall. However, I checked the water meter after an hour of no water usage, and it doesn‘t look like anything is leaking. I‘m just worried I may have caused something to happen in the long-run though.: Most likely it is a copper adapter to a pex or compression fitting. It is cheaper to fix drywall 12X12 hole than it is to fix a flooded home, I'd cut the drywall and replace the entire assembly and secure it well to the framing, no more worries!

Q:Which metal do you like more: Copper or bronze?I like bronze better because it can be forged into weapons more easily.What about you?Thanks in advance for the answers!: Copper

Q:Despite turning off the water at the mains it still continues to leak which makes me wonder whether it is a pipe for the central heating system which was installed after the house was built. There are numerous pipes connected all under the floor, some to the hot water immersion tank. The water is black which might confirm this. I have temporarily plugged it with one of your subscribers suggestions i.e a toothpick but will find it difficult to plug it wither rubber clamps etc if it is still wet.Any suggestions other than calling in a plumber.: a pneumatic themostat?. that means its air controlled. huh?. well water will not cause a fire. never heard of one, im outdated already!! shucksgood luck with it!

Q:I need any information on the health and safety of copper.Like if it's poisonous, fatal, or harmless? Anything like that would be much appreciated. :)Thanks.: copper in human health

Q:when copper was discovered and when it was found: Copper, as native copper is one of the few metals to naturally occur as an uncompounded mineral. Copper was known to some of the oldest civilizations on record, and has a history of use that is at least 10,000 years old. A copper pendant was found in what is now northern Iraq that dates to 8700 BC. By 5000 BC, there are signs of copper smelting, the refining of copper from simple copper compounds such as malachite or azurite. Among archaeological sites in Anatolia, ?atal H?yük (~6000 BC) features native copper artifacts and smelted lead beads, but no smelted copper. But Can Hasan (~5000 BC) had access to smelted copper; this site has yielded the oldest known cast copper artifact, a copper mace head. Copper smelting appears to have been developed independently in several parts of the world. In addition to its development in Anatolia by 5000 BC, it was developed in China before 2800 BC, in Central America around 600 AD, and in West Africa around 900 AD. There are copper and bronze artifacts from Sumerian cities that date to 3000 BC, and Egyptian artifacts in copper and copper alloyed with tin nearly as old. In one pyramid, a copper plumbing system was found that is 5000 years old.
