What type of metal or metals shrink when heated?
538542
though there are many, one of them is:\niceland spar crystal\none reason can be due to the harmonicity of vibrations of the atoms of the substance when their kinetic energy increases

I don't remember the ordering, but there's probably some metal out there that won't react?  Gold, maybe?  For regular metal, that sounds a bit iffy.

On their own, none of those metals react with steam.  Good thing, too, since they are used in metal pipes to carry steam.\n\nThey can oxidize, though, if there is enough oxygen mixed with the steam, however, this would be rare with most boilers.

Change it to 1.27 × 10^4\n\nYour value for Specific Heat of Zn is only 3 sigfigs, thus, your answer can only be up to 3 sigfigs.

Magnesium will react with any gas except noble gases when heated, because of its low electronegativity. In vacuum or noble gas atmosphere it can be heated up to melting point of 625°C, just at or below red glow.\n\nWhile red or white hot iron will oxidize on the surface, the heat released by that process is not sufficient to start a chain reaction like in burning magnesium. The higher melting point of iron depends mostly on the crystal lattice of iron.

does it not need to be reheated and become molten again?

This isn't the final answer, but it is a clue:\n\nhttp://www.thesheetmetalshop.com/pdf_manual/Problem1.pdf

Okay, I'll try this one -\n\nRun this experiment twice (or more times), each time with a piece of metal having different density.  The metal piece should be of adequate size (a sewing needle isn't going to do it), it needs to be big enough to significantly affect the temperature of the water.  You will need to know the mass of the metal (i.e., weigh it) and have a thermometer capable of reading from room temperature up through boiling or so.  Please note this is not going to give you a highly accurate answer, but can give you a ballpark idea (I'm guessing you're probably not doing this in a 500 million dollar lab).\n\nThe procedure:\n\n1)  Measure and record room temperature as T1.\n\n2)  Weigh the metal, call it M1.\n\n3)  Bring a known quantity of water (weigh it, or measure it and convert to weight, call it M2) to a temperature just short of boiling (say 180F to 200F, use the same temperature for each run of this experiment).  Record the temperature as T2, and remove the heat source (take it off the burner, etc.).\n\n4)  Drop in a metal piece at room temperature.  Allow a couple of minutes for heat to exchange.  Make sure you use \nthe same amount of time for each run of this experiment.\n\n5)  Measure and record the new temperature of the water as T3.\n\n6)  Repeat with your other metal samples.\n\nYou can now estimate the specific heat capacity for each metal.  It will not be super-accurate (heat escapes your system, and temperatures won't have completely equalized), but should give you some idea.  Just assume all temperatures did equalize and that no heat escaped for calculational purposes.\n\nSince (you are assuming) the heat which left the water went into the metal, then the product of mass, specific heat capacity, and temperature change should be the same for both the metal and the water (but in opposite directions).\n\nThis means that:\n\n(M1)(c1)(T3-T1) = (M2)(cw)(T2-T3)\n\nwhere c1 is the specific heat capacity of the metal, and cw is the specific heat capacity of water (look it up on Google to get the units you need).\n\nSolving this, you get:\n\n......(M2)(cw)(T2-T3)\nc1 = -----------------\n........(M1)(T3-T1)\n\n(sorry about the dots, I'm trying to keep everything aligned)\n\nRepeat the calculations for each of the metals.\n\nYou will need to calculate (or look up) the densities of each of the metals.  Then, graph density vs. the specific heat capacities you calculated, and see if your hypothesis is true.\n\nHave fun!

The heat from the parts that are burning alters the chemical composition of the paper coating on one side, "shrinking" that side and causing the paper to curl.

All Metals are tend to loose their electrons easily.\nSo if U heat an metal Rod then it's electrons gets energy by heating and start transferring to the other end of the Metal rod. So the other end is seemed to hot

Solid in room temp, but melts in your hand (slightly above room temp)\n\nAlloys quickly with most metals.\n\nYou can read more at the following:

In pretty much all substances, when you heat something (assuming no phase change), the material becomes less dense due to the fact that its volume expands and mass stays constant.\n\nSo if you were to heat a pot of water for example from the bottom on a convection stove, the hot water at the bottom would become less dense than the cooler water on top.  The hot water would rise and it is rises, the cooler water sinks down to take its place.

Its a Metal, hence responds to / is a conductor of heat.\n\nIts fluid so the expansion per gradient of heat would be highest.\n\n\nAll other liquids are not a conductor of heat ( or as good as mercury)

If you are doing it in a laboratory setting, you can mix it with carbon and reduce it to the metal. You will need high temperatures, though.

The charring you are referring to is called "Remelt"\n   It is seen in the EDM process as well.\nI am unfamiliar with the material you are referring to.\n   Can you offer more information?

This really depends on what liquid versus what solid you are heating.  Some liquids are actually less heat conductive that solids.\n\nFor example,  if you have some oil and some aluminum then the aluminum is going to heat up faster than the oil would.

Rust is a chemical reaction involving iron and oxygen.  Melting metal is simply a physical reaction changing the state of its matter, so melting the metal wouldn't get rid of the rust to the best of my knowledge.  IT might however make it easy for you to seperate the rusted and non rusted parts of the metal, but then again it might make it a total mess lol
