Flow of Energy and Flow of Heat Energy

What might cause the food to not cook all the way through?

• Not enough energy reaches the center of the food.

• The energy cooks the outside of the food, and then the food begins to lose heat instead of cooking further

• Energy flows into the food too quickly and is lost before the inside is cooked

• The food conducts energy , so the energy passes through the food without cooking it

How might using a pizza stone instead of a pan affect how the pizza cooks?

• The stone absorbs energy, keeping the crust cooler than the pizza toppings.

• The stone gets hotter than the rest of the oven, so the pizza cooks faster

• The stone transfers energy slowly, so the crust cooks evenly
