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:A parallel-plate capacitor is made from two aluminum-foil sheets, each 3.90 cm wide and 10.3 m longBetween the sheets is a mica strip of the same width and length that is 0.0225 mm thickWhat is the maximum charge that can be stored in this capacitor? (The dielectric constant of mica is 5.4, and its dielectric strength is 1.00 108 V/m.) Please help soonI feel like this should have been easy, but its not.

Q:The few times I have tried to make one, the middle of the cake or a pineapple ring sticks to the pan, leaving part of the cake with no brown sugarHow do I make sure that the whole cake gets coated with the brown sugar and butter? I don't need a recipe; I like the recipe I haveJust some tips on how to get it out of the pan.
Use a cast iron skillet the size for your recipePlace your melted butter and brown sugar in pan before adding pineapple slices, cherries for the center of the slices then your cake mixThe iron skillet ( hopefully a seasoned skillet) will conduct the heat more evenly making it a lovely golden brown when done and turned over on an appropriate cake plateFailing that use a glass pan making sure all areas are covered with the butter after spraying with Pam, or line your cake pan with Aluminum Foil and spray with Pam then proceed as usualWhen the cake cools somewhat turn over and while still warm slowly remove the foil.
Q:I have a ham that I want to cook for dinner tonight, and it is frozen right nowHow long should it take to thaw, what is the safest way to thaw it, and how should i cook it? Thanks!!
It really doesn't matterOne side is shiney and they other dull but its part of the manufacturing process! Wrap it whichever way you like.
Q:I am making an angel costume with huge wingsWhat might be a way to create these wings?
Volunteer to your neighborhood, get a summer season process, become a member of the neighborhood theatre, discuss with the library learn a e-book, take in a passion like fishing or some thing artfulFly a kite, cross to the park, cross to the lake/seaside, have a summer season barbeque.
Q:I worry my fish may be sickI had an small Algae Eater in, but he diedSo, I wonder if he was sick, and if so, could my fish have caught something.They swim, eat, and are very livelyBut I notice 1 has a red spot on his headIs that a illness in Goldfish? Or could it just be some kind of bumpThey swim fast alot, and sometimes knock over things in the tank, and get crazy when you first tern the light on them.So, could it be a bruise, or are red spots/bumps a bad sign in goldfish?
Your algae eater died because you didn't feed itThey can not survive on algae growing in a tank, and no fish will eat other fish wasteYour aquarium is probably too small and the high concentrations of ammonia is causing chemical burns on your fish The first gold fish needs 20 gallons, every goldfish after than needs another 10 Algae eaters are tropical fish, gold fish are cold waterThey are incompatible and this could have also lead to fish deaths.

Look at the group : Group 1 (Li - Fr) 1 valence electron Group 2 (Be - Ra) 2 valence electrons Group 13 (B - Tl) 3 valence electrons Group 14 (C - Pb) 4 valence electrons Group 15 (N - Bi) 5 valence electrons Group 16 (O - Po) 6 valence electrons Group 17 (F - At) 7 valence electrons Group 18 (He - Rn) 8 valence electronsIn transition metals Groups 3 - 12 it is a little bit more difficultFor early transition metals, Groups 3 and 4 you can say that the group number also is the number of valence electrons, so Sc, [Ar]3d^1 4s^2 will have three valence electrons, Sc2+ and Sc3+ do exist, Sc2+ is [Ar]3d1 and Sc3+ is [Ar]For middle to late transition metals, the s electrons are the ones considered valence electronsSo Zn [Ar]3d^10 4s^2, only the 4s^2 are valence, Zn2+ is [Ar]3d10Cu, since it has an anomolous electron configuration, [Ar]3d^104s^1, we can have Cu+ [Ar]3^10 and Cu2+ [Ar]3d^9, given that the highest charge cation is +2, I will say copper has 2 valence electron.
Q:Candy canes- do I have to leave them in the oven?
umma scarfi like knitted gloves too! for a dog i would probably get a knitted bed or blankie, maybe a sweater (depends on dog)
