Aluminium foil acts as a total barrier to light and oxygen (which cause fats to oxidise or become rancid), odours and flavours, moistness, and germs, it is used broadly in food and pharmaceutical packaging. The purpose of aluminium is to make long-life packs (aseptic processing|aseptic packaging) for drinks and dairy goods, which allows storing without refrigeration. Aluminium foil containers and trays are used to bake pies and to pack takeaway meals, ready snacks and long life pet foods.
Aluminium foil is widely sold into the consumer market, often in rolls of 500 mm (20 in) width and several metres in length. It is used for wrapping food in order to preserve it, for example, when storing leftover food in a refrigerator (where it serves the additional purpose of preventing odour exchange), when taking sandwiches on a journey, or when selling some kinds of take-away or fast food. Tex-Mex restaurants in the United States, for example, typically provide take-away burritos wrapped in aluminium foil.
Aluminium foils thicker than 25 µm (1 mil) are impermeable to oxygen and water. Foils thinner than this become slightly permeable due to minute pinholes caused by the production process.
Aluminium foil has a shiny side and a matte side. The shiny side is produced when the aluminium is rolled during the final pass. It is difficult to produce rollers with a gap fine enough to cope with the foil gauge, therefore, for the final pass, two sheets are rolled at the same time, doubling the thickness of the gauge at entry to the rollers. When the sheets are later separated, the inside surface is dull, and the outside surface is shiny. This difference in the finish has led to the perception that favouring a side has an effect when cooking. While many believe that the different properties keep heat out when wrapped with the shiny finish facing out, and keep heat in with the shiny finish facing inwards, the actual difference is imperceptible without instrumentation.The reflectivity of bright aluminium foil is 88% while dull embossed foil is about 80%
- Q: If a positively charged hand touches a neutral state aluminum door knob with a composition of 3 valence electrons, 8 outer electrons, and 2 inner electrons, the three valence electrons will jump towards the hand and the door knob will turn into ionized aluminum (Al3+).How does the aluminum get the 3 valence electrons back and return to neutral aluminum (Al) ???
- For the charge you are talking about, the amount of electrons is not too largeIt can take missing electrons from the surroundings.
- Q: Light of wavelength 200 nm falls on an aluminum surfaceIn aluminum 4.2 eV are required to remove an electronWhat is the kinetic energy of (a) the fastest and (b) the lowest emitted photoelectrons? (c) What is the stopping potential? (d) What is the cutoff wavelength for aluminum?
- these can be found from your chapter on photo electric effect energy of photon will liberate the electron it will lose 4.2 eV in moving to the surface than it will move with kinetic energy of whatever the energy is left so the photon is 200 nm E h f f c/L then E h c/L h 4.14110^-15 eV units E 4.14110^-15310^8/20010^-9 E 2.0705310^0 E 6.2115 eV E K + Wo K E - Wo K 6.2- 4.2 2.0 eV so the highest K will be 2.0 eV the lowest K will be of course 0 eV (because it could hit more than the usual number of atoms and loose all its energyc) what is the stopping potential if the highest Ke of the electron is 2.0 eV then to stop any electrons from having any Ke we just need to have a force pushing them back with 2.0 eV potential I would think this is -2 V W eV solve for V this means if the V is reversed it will have enough Electric field to stop the electrons with the highest Ke from hitting the anode V K/e V 2eV/e 2V so a stopping voltage of -2V is required to stop the electrons it must be negative because electrons are repelled by a negatively charged plate d) the cutoff wavelength is just the lowest energy photon that will just excite the electron E Wo since hc/L Wo solve for L L hc/Wo use h 4.14110^-15 L 2.95810^-7 L 295.8 nm thats all there is to it just think it through
- Q: sugar maple syrup and bi carb soda.plz help!
- Maple Honeycomb Ingredients: 3/4 cup maple syrup 2 cups granulated sugar 1 generous tbsp baking soda 1/4 cup water Prep: Prepare a rimmed baking sheet by lining it with aluminum foil and spraying the foil with nonstick cooking sprayCombine the sugar, maple syrup, and ? cup water in a large saucepanYou want to use a saucepan large enough so that the mixture can triple in size and still be safely containedStir the ingredients together until the sugar is completely moistenedUsing a wet pastry brush, wipe the sides of the saucepan to remove any stray sugar crystalsInsert a candy thermometer and cook the mixture over medium-high heat, without stirring, until the temperature reaches 300 degreesOnce the candy is at the proper temperature, remove it from the heat and add the baking soda all at onceImmediately whisk the candy to incorporate the baking soda, and be careful—it will foam up a great deal! As soon as the baking soda is incorporated, pour the candy carefully onto the prepared sheetAllow it to cool and harden completely, then break it into small pieces.
- Q: All the recipes I see online make too muchand I had to throw some out cuz I didnt finish it or left it out too long2 and 4 servings is goodI want to cook for my boyfriend who's gettin out da navy, so please 2 to 4 servings!
- Easy Arroz con Gandules SERVINGS 4 INGREDIENTS 2/3 cubanelle or italian frying peppers, diced 1/3 onion, chopped 2 cloves garlic, minced 1/3 bunch cilantro, finely chopped 1 tablespoon olive oil 1/3 (15 ounce) can tomato sauce 1/3 (.25 ounce) package Spanish seasoning 1 cup uncooked white rice (medium grain perferred) 2/3 (15 ounce) can pigeon peas, drained 2 cups boiling water DIRECTIONS Place green peppers, onion, garlic and cilantro in a blender or food processor, pureeThis mixture is called soffrito, it is your seasoning baseIt can be stored in an airtight container and refrigerated for up to 2 weeks or frozen for up to 6 monthsPlace 3 tablespoons olive oil and 6 tablespoons soffrito in an 8 quart saucepanCook for 3 or 4 minutes to release oilsPour one can of tomato sauce and the Spanish seasoning packet into the saucepan, mix wellAdd 3 cups rice to the mixture and stir until the rice is coatedStir pigeon peas into the mixture and add boiling waterCover the pot with aluminum foil and a pot lidReduce heat to simmer and cook 45 minutes or until rice is tender.
- Q: There are two sides: one shiney, one notWouldn't shinier side facing the food reflect and retain heat better?
- There might be some very slight difference in the albedo between the 'shiny' and 'dull' sides of the foil, but there's probably more variation in your oven temperature than there would be a difference between which side of the foil you use The shiny side is created when the roll of aluminum foil is spun off the rollers in the packaging plant, and the side against the roller gets burnished as it reels outBoth sides are very nearly equal in their heat reflection abilities, and so you can use either side without fear that the other side may have 'worked better'.
- Q: I have three questions this is only for people that know what I am talking aboutFirst can I make the Volksplane using aluminum tubes? Second should I build a two seat or one and would it cost more for a two seat? Lastly where can I get the plans for free?
- Plans for free are not likely unless, like the other guy said, you can find a friend that doesn't want/need theirs any moreOne or two seats is the ultimate homebuilder questionIf you build it with tubing, it's not the Volksplane any more but your own designFind your local EAA chapter and try those questions there.
- Q: How many electrons will each element gain or lose in forming an ion? State whether the resulting ion is a cation or an anion.a)strontiumb)aluminumc)telluriumd)rubidiume)brominef)phosphorous
- Yes for me because when I say tinfoil, I say aluminum right after that!!!
- Q: Which of these Airsoft guns is better?
- no not usually my moms never did as long as the cage is clean and you bath them they should be fine
- Q: Best way to warm up roast Turkey so it doesn't dry out?
- DependsEscalator if I can find one (like at malls and stuff), if not, stairsIf I'm going up like a billion floors at a hotel or something, I prefer to take the elevatorI think elevators should be saved for the physically disabled and young children (in strollers), or if someone is transporting a heavy object.
- Q: Express as a law, the relationship between position on periodic table and number of electrons in the outer orbit.Please explain.thx
- I take it off the bones and simmer it very slowly in barbecue sauce then use if for sandwichesYou can do this with whatever sauce you like.you can also simmer it in cream of mushroom soup or whatever soup you like then put it over rice.
