When water freezes it expands, as opposed to practically all other liquids. (For this reason ice fortunately forms on the TOP of ponds and lakes.) The expansion causes pressure to build up that could eventually burst the pipe. However, most water pipes burst because, as the ice builds up in the direction of the pipe, the water pressure continues to build up downstream from the growing volume of ice, that is between the ice and the faucet's. (Water pressure does not appreciably increase upstream as there is much more water on this side.) This enormous buildup of pressure can eventually cause the strongest of pipes to burst. It is a good idea to leave a faucet dripping if the pipe leading to it is in danger of freezing. Not only does this significantly reduce the chance of the water freezing in the pipe, but it keeps the water pressure from building up to dangerous levels that can cause bursting.
Although I am unsure of the exact time it takes for pipes to freeze, due to a variety of possible temps., pipes, water temp, etc., I know on a day that is far below freezing you should leave the water in your faucets running a small amount to avoid freeze.
ANS 2 - If you are in any danger of pipes being frozen, there are now many ways to avoid this. Insulation around exposed or unprotected pipes is the easiest if you can get at all the pipes. In my area pipes freeze often. -I protect against this by extensive use of electrical 'heat tape' . I live in a mobile home and have a 3 ft high crawlspace, so I wrapped 'heat tape' all around my incoming water pipe. This tape carries a thermostat, and comes on at 1 degree C, giving a very small amount of heat to the pipe, keeping it from freezing. These tapes are available in all Plumbing stores and most big box stores including HD. -Cost is about a dollar per foot. -Well worth it !
When water turns to ice it expands, so anything that gets destroyed happens then.
But if the pipe is frozen solid, there isn't anything to show what's happened - as the ice can't make it through the crack anyhow.
The ice will act as a plug, blocking the crack/hole.
It's first when the ice turns back into liquid as it can begin to seep through the crack and show that it's there.
Because ice (solid water) has a higher volume than liquid water.
As water freezes the molecules stick together with hydrogen bonds but with large gaps in between thus the volume increases and expands
If the copper pipes are full and the water is trapped, the pipes will split at the weakest point when exposed to continuous freezing temperatures. A testament to the power of crystallizing water.
if water freezes in pipes it will break the pipes, literally.
Yes, copper pipes can burst when the water inside them freeze. This is because, when the water freezes, it expands with a considerable amount of force, against the pipe, bursting it.
because when water freezes it expands causing the pipe to burst
Because water, almost uniquely, expands when it freezes.
If the pipes are filled with water, they are more likely to crack. The reason for this is because the water expands when frozen, cracking the pipes.
Soilds an liquids have a higher solubility at higher temperature (with extremely rare exceptions).Gases are more soluble at low temperature.
No. It takes a combination of pressure and temperature to liquefy some gases. Hydrogen and helium were the last gases to be liquefied and that was with pressure and extremely low temperature.
If the temperature is low , the air will feel cold.
Because mercury has an extremely low melting point. It is the only liquid metal at room temperature.
in the sence of chemistry many reaction occured at the low temperature....dis is main advantage of low temprature
To protect them from frost damage. In cold weather, 'standing' water in cold pipes can freeze if the temperature drops low enough. When water turns to ice, it expands - which could cause the pipe to burst. However - you wouldn't know if it had burst until the ice had thawed !
Copper has extremely low reactivity with water which is why it is used to make water pipes.
Hypothermia
Heavy weight mild steel with screwed fittings bspt. == Normally galvanized pipes are not used for steam. Mild steel with screwed or welded fittings are the norm. Pressure and temperature are very important factors to be considered in what type of materials to be used. Steam even at low pressures can be extremely dangerous. Answer In hign temperature application nomally the alloy steel pipes are used ANSWER: Mild Steel Seemless pipes, thickness dependent on the pressure rating to be used.
If you are on city water, a large pipe has burst somewhere causing pressure to drop drastically. If you are on a well, a problem has occurred in your pump, or your pressure tank, or the main pipe between well and house. In extremely cold weather pipes from a well can burst. Many well heads (at least in my area) are very inadequately protected.
It allows doctors to know if a person is well. An extremely high temperature can indicate a fever, while an extremely low temperature can suggest other problems.
By keeping it at an extremely low temperature (−183 °C) or at an extremely high pressure

A superconductor superconducts ONLY at extremely low temperature.
Absolute magnitude: they are extremely bright. Temperature: their surface temperature is fairly low.
Tthat is dangerously low because the normal temperature is supposed to be 37 degrees (98.6 degrees Fahrenheit).
No, helium will turn into a cryogenic 'liquid' not ice, as it is cooled to extremely low temperature's.
