Q:a chunk of aluminum is at 220degees C is thrown into water that is initially 50degrees C?
(A) Let the aluminum is of m kg, than :- =Q(gain) by water = Q(loss) by aluminum =m x s(water) x delta t*C = m x s(aluminum) x delta t*C =50 x 4187 x (100 - 50) = m x 897 x (220 - 100) =m = 97.25 kg (B) Let the amount of water boiled off is m kg =Q(loss) by aluminum = Qwater(50*C to 100*C) + Q100*C(water to vapor) =500 x 10^-3 x 897 x (220 - 100) = 50 x 4187 x (100 - 50) + m x 2257 x 10^3 =m x 2257 x 10^3 = -10413680 =No water will be boiled off as the energy provided by aluminum is less than required to raise the temperature of water to 100*C.
Q:Why Does Wet Aluminum Stink? ?
Believe it or not, aluminum is a very reactive metal. In its normally encountered, dry form, aluminum reacts with the oxygen in the air to form aluminum oxide, which coats the metal and protects it from further reaction for the majority of household purposes. However, putting aluminum into water causes this oxide layer to be destroyed, allowing the aluminum metal to once again become reactive. From that point it may react with a host of other chemicals from acids to bases, forming different aluminum salts and gases that may be smelly, or catalyzing chemical reactions that too can stink. For an example of how reactive aluminum is compared to aluminum oxide, get some household lye (NaOH) pellets, some water and a piece of aluminum foil. Place some lye on top of the aluminum foil, and add a little bit of water. At first, it will appear as if nothing is happening - at this time however the water is destroying the aluminum oxide layer. When enough of the oxide layer is penetrated (usually within 30 seconds to a minute), the NaOH proceeds to react with the aluminum metal to release hydrogen gas. This reaction quite literally eats through the metal. Be careful when doing this experiment as NaOH is caustic and hydrogen gas is flammable.
Q:Aluminium properties????? 10points?
1) Aluminium is very light weight 2) Aluminium naturally generates a protective oxide coating and is highly corrosion resistant. 3) Good electrical and thermal conductors due to its delocalised electrons 4) Aluminium is a good reflector of visible light as well as heat, and that together with its low weight, makes it an ideal material for reflectors in, for example, light fittings or rescue blankets. 5) Aluminium is ductile and has a low melting point and density. I hope this helps? :)
Q:Tin foil and aluminum foil can stop / shielding electromagnetic signals?
Tin foil and aluminum foil blocking / shielding electromagnetic signals, regardless of frequency is M, G, or more, can be shielded.Harmless to the human body, you can rest assured that the use ofThe food sold in the supermarket is very good with foil, so you can try it
Q:How to wash away the oil of aluminum foil products after being pressed?
I suggest that you can use the volatile punching oil since it won't be rudimental.
Q:Why use aluminum foil packaging of cigarettes?
Eighties, as the inner liner of cigarette aluminum foil and aluminum foil rolling main Metallized, now, composite aluminum foil material has become a development potential, which has light, high barrier and gas, water corrosion resistance, when the temperature changes rapidly, without any material deformation.
Q:How does aluminum foil bag should be heat-sealed?
If you don't vacuumize bags,heat-sealing machine is ok. Some heat-sealing machines have hand grips, some are pedaled or with belt wheels. Prices vary with different manufacturers. If you want to vacuumize bags, a vacuum machine is ok. After the vacuumizing process, the vacuum machine is directly sealed.
Q:what is a macbook aluminum unibody? is it a case or laptop?
aluminium unibody is referring to a specific model of the macbook, if you are buying a aluminium unibody macbook you are purchasing the whole macbook, complete and ready to use. hope this helped
Q:Is it bad to burn aluminum foil?
No. The aluminum will usually not burn. At a temperature in excess of 1150 degrees, and being exposed to an open flame at the same time, will result in the aluminum burning. On a barbecue, you will only have a few hundred degrees. When aluminum burns, it will naturally produce aluminum dioxide, which is not toxic. You don't have anything to worry about. Aluminum only burns in fine powder form, or when it is melted (exceeding 1150F)
Q:can use aluminum foil to shield the loudspeaker box wire?
It does little help. In principle, since the loudspeaker wire is the terminal of audio device, common interference will not influence its sound effect. Therefore, a shield is not required. Common wires for strong electricity should be laid by poling. However, the wires for weak electricity such as telephone wire, reticle, TV wire or audio wire should be laid through other pipelines. Thus it has little correlation with strong electricity wire with smaller interference. When laying the loudspeaker wire near to the strong electricity wire or laying them at the same time, the insulation between the loudspeaker wire and strong electricity should be taken as a priority. It is recommended to lay the loudspeaker wire at a distance from the strong electricity wire in case of electric leakage.
