A sponge cake is cooked by the heat transfer method of convection.
Heat transfer in an oven when baking a cake occurs through convection, conduction, and radiation. The oven's heating element or gas flame produces heat, which is then transferred to the air inside the oven through convection. The hot air circulates around the cake, transferring heat to the batter through conduction. Additionally, the walls of the oven emit infrared radiation, which also contributes to heating the cake.
A combination of heat paths will be in effect within an oven. The main method of heat transportation will be radiation from the oven heating element to the surface of the cake which will heat the outer surface of the cake. Conduction will them allow this heat to transfer to the interior of the cake via contact paths between each molecule of cake mixture. Conduction will also occur between any air particles which are in direct contact with the heating element, and should they then come into contact with the surface of the cake conduction will again take place between the heated air particle and the surface of the cake. Convection will of course take place in the oven as well.
Baking.
because you have left it to long in the oven,its over cooked

Baking a cake in the oven is a chemical change. The heat from the oven causes the chemical reactions in the ingredients (like flour, eggs, and sugar) to take place, resulting in a new substance with different properties (cake).
Conduction occurs when the heat is transferred from the inside of the solar oven to the cooking vessel through direct contact. Radiation occurs when the heat is transferred through electromagnetic waves from the solar oven to the food being cooked inside.
Yes, energy is transferred in a solar oven when making a s'more. The solar oven uses the sun's energy to heat up and cook the s'more ingredients (marshmallow, chocolate, graham cracker) by transferring heat through the enclosed space of the oven.
Heat is transferred by convection and by radiation in a conventional gas oven. In an electric oven heat is transferred by radiation only. In a microwave oven, radar waves bombard the molecules within food, bouncing them around enough that the friction produced causes heat to build up within the food.
Either cooked too long in the oven or once cooked has been left out to cool for too long.
When baking a cake, oven racks should be placed in the middle position to ensure even heat distribution and proper baking.
