Nope you can't. Despite the fact that both are oils, they have different refractive indexes, which mean that they refract light differently. That means what you'll see in the microscope would be different. Cooking oil is made from purified fats of a plant origin, while immersion oil is similar (or is the same) to mineral oil. :)
Yes, you can. But have to heat it up to 60C or make biodesel(cook cooking oil for 1 to 4 hours in 60C).
in many dessert pastries and cakes you can
YES, the flavor may not be what you are used to , but the chemistry is the same.
Vegetable oil is cooking oil.
butter or PAM!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
You could substitute shortening for oil in a cake mix, but it is not recommended. The resulting cake made with shortening will have a noticeably different texture and mouthfeel. Yes you Can. Shortening.. or Hydrogenated Oil is basically poison anyways.
Shortening is the fat or oil used in cooking. It can range from lard to olive oil, depending on the recipe.
It depends on what you are baking or cooking. Vegetable oil can substitute in some cases. Although it will change the characteristic of your end product because vegetable oil has less "shortening power" than vegetable shortening. Butter can substitute too but you would have to increase the volume and there is the risk of burning depending on what you are making. Lard can substitute too. Its really hard to give an answer that is good, safe without knowing what you are using the shortening for. If you are frying something it is another different matter too.
Use the same amount of butter as you would shortening. In bread, a tablespoon of butter can be used instead of a tablespoon of shortening. The same amount of canola oil is even healthier.
Yes, you can melt shortening and use in a cake recipe. It will change the texture and possibly add heaviness to the cake, but it will still be good.
Not all shortening is oil, but all oil (consumable oil, that is) is shortening. Shortening is another word for fat used in cooking, especially baking. The most common shortenings are butter and margarine and, to a lesser degree, Crisco. Other oils can be used, too. (And some low-fat recipes substitute apple sauce or prune butter for traditional fat-based shortenings.)

Yes, just melt the shortening and let it cool before adding it to the batter.
Yes, in some cake recipes, canola oil can be substituted for shortening.
