Question
Solar Cooker
A group of students has decided to design a solar cooker. These devices use energy from the Sun to help cook food. First, the students plan to measure the efficiency of the solar cooker, and then they will test different improvements to their design. The initial design of their solar cooker is shown in Figure 1.

The students will first add a measured amount of water to the cook pot. The solar cooker can then be placed in direct sunlight to begin cooking food.
As ultraviolet light from the Sun is transmitted through the glass, the light is absorbed by the black-colored interior of the solar cooker. The black-colored interior then emits thermal infrared radiation as heat waves. Most of this radiation cannot pass back through the glass, causing heat to build up inside the solar cooker and the cook pot. Only the thermal infrared wavelengths of radiation can cook the food. This process of trapping radiation is called the greenhouse effect.
The students note that all of the materials used in the solar cooker are able to conduct at least a small amount of heat. They also observe that more sunlight is transmitted through the glass when it strikes the surface more directly.

To arrange the different parts of the solar cooker design from least to greatest based on the average kinetic energy of the particles, we can consider how temperature affects the motion of particles in different states of matter.
1. **The solid particles of the solar cooker walls** - Solids have the least kinetic energy because their particles are closely packed together and can only vibrate in place.
2. **The gas particles outside the solar cooker** - Gas particles outside might have some kinetic energy due to temperature, but they are generally at a lower temperature when compared to the particles in the cook pot.
3. **The gas particles inside the solar cooker** - These particles are getting heated by absorbing thermal infrared radiation, increasing their kinetic energy.
4. **The gas particles inside the cook pot** - These gas particles, being in direct contact with the heated water (which is heated by the black interior), will have the highest average kinetic energy.
So the order from least to greatest average kinetic energy would be:
1. The solid particles of the solar cooker walls
2. The gas particles outside the solar cooker
3. The gas particles inside the solar cooker
4. The gas particles inside the cook pot
