Does cooking more than one thing in the oven take longer?

454 viewsOtherPhysics

Ex: Cooking 2 pizzas (same temp/time needed) in the oven at the same time. Can I just set the same temperature and time as cooking one, and they’ll both come out perfect still? Why or why not? (Let’s ignore differences in cooking based on which rack the pizza is on lol)

I don’t cook much lol, so I’m trying to wrap my head around how cooking “consumes(?)” heat energy. More food mass isn’t going to *reduce* the temperature in the oven or anything… is it? And, the food masses aren’t connected, so not sharing heat distribution(?), so that seems like they shouldn’t affect each other?

Think of it in terms of energy.

The pizza maker says it takes 10 minutes at 200c. What’s really happening is that for 10 minutes, the energy in a 200c place is going to the pizza. This energy makes it ok to eat. 

But 2 pizzas means the energy is going to two places. 

Now, there’s enough energy that the two pizzas don’t need twice the energy- some that would’ve been wasted otherwise goes to the second pizza. 

But overall you still need a bit longer, to ensure there’s enough energy going to the two pizzas to cook them properly.
