Pancakes

My sister Abby loves to make pancakes for breakfast. She makes three small pancakes at a time using one pan. How does this cook all of the pancakes evenly? This is where physics comes into the equation. The flame is concentrated in the middle of the pan, so wouldn't that be the only place where the pancakes would be able to be cooked? One would assume so, but due to energy and particle movement, the entire pan is able to cook a pancake, even though the flame is not directly under that spot. The flame heats up the molecules in the pan directly above it, causing the heat energy to be converted into kinetic energy. As the molecules then move rapidly, bouncing off one another, the collisions with other molecules in the pan transfer energy from one molecule to another, transferring energy across the whole pan. The kinetic energy in each of the molecules and collisions cause the entire pan to heat up. This is why it is possible to make three pancakes by using just one pan.
