Yes, in a normal oven it will catch crumbs, grease, oil etc.
But DON'T put it in a microwave oven, or any other metal for that matter.
Of course, you should use foil to protect your baking sheet.
no you can not
Yes it can.
Aluminium foil disintegrates in a convection oven because the heat rays of the oven hits the aluminium foil but gets reflected by the foil. Thus, the oven over heats and the aluminium foil disintegrates.
Yes, you can use foil in convection ovens and regular ovens alike (despite the different names all ovens are convection ovens, ovens labeled convection ovens are just faster). However, NEVER and I mean NEVER use foil in a microwave. Then it will go BOOOOOOOOOOMMMM!!!!!!!My Oster convection oven manual has a safety warning regarding foil: "Do not cover the oven tray with metal foil. This will cause overheating of the appliance."

yes, foil does keep cooking oil clean.
You don't have to. Some people like to wrap it because they won't have to clean the bottom of the stove afterwards. I never use foil (makes the yam a bit soggy to me). I just put the yams ontop of some foil and bake them that way.
clean foil
The foil reflects the heat back to the radiator thus reducing convection off of the radiator.
Heat can be transferred by 3 mechanisms: conduction, convection, and radiation. When food is covered by aluminum foil, the foil does reduce convection a bit because the air next to the food is trapped there. A bigger effect is the reflection of the heat by the foil. Rather than continuing on its path to dissipate into the surroundings, the heat is reflected by the foil back into the food, thus helping to keep it warm.
always keep your hands and area you are cooking in clean, and always cover your food with aluminum foil or a very clean towel
i think the aluminum foil goes at the bottom, but that's just what i think.
i would assume yes but only if you are only using the oven portion and if the oven has a separate heating process from the microwave. do not use aluminum foil while microwaving, it doesnt work to well.
Answer: No! Do NOT put aluminum foil in the bottom of an oven, I did that and it ended up melting and baking on the bottom of the oven and it's almost impossible to get it off.
