Preheating is necessary because it ensures that the oven is at the temperature that you want it to be when you start cooking. If you do not preheat, you will probably end up with undercooked food, because you did not actually cook it at the right temperature for the right amount of time.
Preheating the oven before baking is necessary to ensure the food bakes thoroughly and evenly throughout. It also gives the leavening a head start in rising before the product cooks and sets and since ovens do not preheat at the same rate, it gives a consistency in the timing of recipes.
I'm guessing you mean preheating. Having the oven at the correct temperature creates something called "oven spring" which allows the heat activated leavening to do its job before the product starts to cook.
For most baking purposes, it is not only better to preheat the oven but it is absolutely necessary.
Preheating an oven will cause whatevr your baking to cook evenly
Check the recipe before cooking. Sometimes preheating is, and sometimes is not, necessary.If you need to cook something in the oven for a specific amount of time at a specific temperature, then it must be cooked at that temperature the WHOLE time.If it takes 10 minutes to preheat it to 300 degrees, and you put the food in WITHOUT preheating, you undercook it.And if you out the food in WHILE preheating, you end up overcooking it.
When baking cupcakes an average preheating temperature would be around 325 degrees Fahrenheit for non-stick pans, or 350 degrees for shiny metal or glass. Have fun baking!
YES ! (:
You can bake thin cut bone in pork chops by first preheating the oven to 400 degrees. Then place the chops on a foil lined baking pan and cook for about 8 to 10 minutes depending on actual thickness.
no, but test it on the inside of your wrist first.

Preheating is necessary for those plastics who are hygroscopic in nature. Mostly all engineering plastics are need to be preheated before processing. If we do not preheat the material than the present moisture in plastics material will react with molten plastic during processing and will cause breakage of polymer chain and results the poor visual appearence (Silver Streaks) & lower mechanical properties of the molded component. Plastics can be preheated thro Hot air oven or Material hopper dryer. And the preheat tempreature may very plastics to plastics. Answer By: Sachin Porwal, Follow me on Twitter: @sachinporwal

I'm sorry, but you can't substitute oil and water for eggs.
