网页It does get hot, but since it is so thin, and an excellent thermal conductor (being metal), it radiates/conducts away all of its heat so rapidly that it cools off much faster than anything else. Answer 3: Actually, aluminum foil does get hot when it is in the oven.

网页Answer (1 of 6): Because, pragmatically, there is no temperature that’s “too hot to touch”. You have to take mass into account. As an analogy, which is hotter: the heating coils on a stove, or the sparks thrown off when you grind metal? The answer is the sparks. They’re white-hot, which means th...
网页2022年6月20日 Why can you touch aluminum foil in the oven. Aluminum foil is made of metal, and metal is a conductor of heat. That means that if you touch aluminum foil while it’s in the oven, you’re going to feel the heat. The heat will transfer from the foil to your skin, and you could end up with a serious burn. So, it’s important to be careful when ...
网页The reason why aluminum foil doesn’t get hot is because it has a very low thermal conductivity. This means that it takes a long time for heat to travel through the foil. If you’ve ever cooked with aluminum foil, you know that it can get pretty hot. But why doesn’t the aluminum foil itself get hot?
网页Its the quantum for how much energy it takes to raise something by one degree. Aluminum has a very low specific heat, meaning, heating/cooling aluminum involves very little actual energy transfer. There fore, a hot piece of foil only puts a tiny amount of energy into your fingers before its the same temperature as your fingers. 2.
网页2001年3月16日 When the oven door opens, that aluminum foil is at the 150 to 200 degrees as the oven. However, notice that the aluminum foil is very thin. There is very little actual aluminum and it is spread over a relatively large area (standard aluminum foil is about 0.0007 inches thick; heavy duty foil is about twice as thick). As a result cool air ...
网页Why does aluminum foil not feel hot after it’s taken out of an oven? Because it's so thin that it cools down immediately. Also metal conducts temperature much better than other materials, so the change from got to cold happens even faster. But take the same foil, scrunch it up into a tight ball, and try again. You'll burn your fingers. 6 1

网页2014年5月19日 The foil has two effects: it insulates and reflects. Thermal insulation does not offer immunity from heat. It reduces the flow of heat. In other words, it delays. In this case, the actual insulation isn't caused by the aluminum foil (which conducts quite well) but by the air layers that it traps.
网页2022年3月2日 Aluminum foil does trap heat, but it traps moisture, too. This means your potato will end up more soggy and steamed as opposed to baked and crisp. In fact, the Idaho Potato Commission is adamant that baking

网页Why does an aluminum pan get too hot to touch in the oven but aluminum foil does not? The foil is thin and has little mass so the heat it holds is small and easily absorbed by your larger, cooler fingers. And being thin, the crossection able to conduct heat toward your touch point is small so whatever heat arrives isn't too much for your flesh.
网页The foil is probably bonded to the oven, just like aluminum foil can deposit on the surface of (acidic) lasagne, no melting required. However, this isn't the point: the foil is there, and it doesn't really matter how it got there, but it does matter whether the oven is safe to use.

网页The foil is at 350 degrees in the oven, but almost as soon as it get hit with cooler air (like opening the oven) it cools off. Also, the amount of heat energy in that thin piece of foil is so small that you don't even notice it much of the entire cooling of the foil is achieved by "heating" your finger. A tiny drop of heat in an ocean of hand.
