The heat source is probably from a flame, an oven, or from an electric stovetop. The metal pan or sheet helps to trap the heat and transfer it to the cookies. If there is too much heat or the heat is applied for too long, the the cookies will burn.
Depends on what you want to use it for. It's good if the base of a frying pan conducts easily as it means it'll heat the contents fast. It's bad if the handle of a frying pan conducts easily as the handle will get too hot to hold and burn you.
Because it conducts heat.
Try spraying the pan. the sugar is the hottest substance in the cookies and the baking sheet has the most concentrated heat so the combination of the sugar and the concentrated heat causes the bottom to burn
Tin pan, because it conducts heat better than a plastic pan.
through radiation
BEANSSSSSSS!!!!!!!!! and hotness also not stiring it enough
If the pan is darker it attracts more heat so the cookies are done faster. I would recommend using a light pan as they won't be burned too quickly.
An example of conduction in heat transfer is when you touch a hot pan on the stove, and the heat is transferred from the pan to your hand. The metal of the pan conducts the heat to your skin through direct contact.
they bake faster because there closer to the heat
Because the stove burner conducts the heat through the pan to cook the food.
You burn yourself when you touch a hot metal frying pan because metal conducts heat very efficiently. When your skin comes into contact with the hot surface, heat rapidly transfers from the pan to your skin, raising its temperature to the point that it can cause damage and pain. This reaction triggers pain receptors in your skin, leading to the sensation of burning. Additionally, the body's natural response to pain prompts immediate withdrawal from the source of heat to prevent further injury.
Because heat spreads from the outter edges of the pan and then into the middle so there you go!
