when would you preheat an oven?\na few minutes before youre ready to use it\nright when youre ready to use it
Answer
Brief Explanations:
Preheating an oven is done to reach the desired cooking temperature in advance. It should be started a few minutes before use to ensure the oven is at the proper heat level when the food is placed inside. Starting it right when ready to use won't give it time to reach the correct temperature.
Answer:
a few minutes before you're ready to use it
