How heat produced an hot pandesal in an oven toaster?

In an oven toaster, heat is produced by electrical resistance in the heating elements, which generate infrared radiation. This heat is transferred to the pandesal through convection and conduction, causing the dough to rise and the exterior to brown as it bakes. As the temperature increases, the moisture inside the pandesal evaporates, creating a soft, fluffy interior while the outer crust becomes crisp. The combination of these processes results in a delicious hot pandesal.
