The given diagram demonstrates the sequence of cooking food using a solar box oven.
Overall, it can be seen that there are 6 steps in the sequence, starting with preparing a black cardboard box, and ending with the food being cooked at high temperature.
The first four steps involve the process of setting up the solar box oven. Initially, a box is prepared that can absorb solar energy to heat food. After this, a bunch of vegetables are put into the pot before being conveyed into that cardboard. Subsequently, an introduction of a larger box to contain the previous box that the bottom of it is filled with materials including shredded newspaper, grass or sawdust in order to heat more effectively, ready for the next stage.
Turning to the remaining steps, the cover of the larger box is sealed with a foil cover and a glass lid on top to create a greenhouse effect. Moreover, the entire set up must be exposed to direct sunlight, ensuring that the temperature reaches up to 82 degrees Celsius. Finally, The black box absorbs the heat and maintains it until the cooking process is completed.
