Depends upon the oven you use (if gas or electric) but normally pre heating must be done until the desired temperature is already achieved.
You can determine when the oven is done preheating by waiting for the preheat indicator light to turn off or by using an oven thermometer to check if the desired temperature has been reached.
Preheating before baking a cake typically takes about 10 to 15 minutes.
get it done
A temperature of around 350-375 degrees Fahrenheit is considered warm when preheating an oven.
Depends on what you have done to hurt yourself
Gas and charcoal barbeque grills need to be preheated before they are used. This is so that food cooks evenly and so that food does not burn on the outside without cooking on the inside. Most grills take between 20 and 30 minutes to fully preheat. Charcoal grills should not be used until the charcoal has burned down and become coated in white powder. Preheating should also be done with the grill cover closed so that the grates inside become hot to prevent food from sticking.
Until it is well done.
Meatballs should be cooked for about 20-25 minutes in an oven at 375F to ensure they are perfectly done.
YES ! (:
Preheating in a fluorescent light helps to initiate the ionization process in the lamp's phosphor coating, which is necessary for the lamp to emit light efficiently. By preheating the electrodes, the lamp is able to start up quickly and reach full brightness faster than if the electrodes were not preheated.
I wouldn't suggest preheating them, because boston cream pie's are served cold or room temperature.
The recommended oven warming temperature for preheating before baking is typically around 350 to 375 degrees Fahrenheit.
