Question
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 from least to greatest based on the average kinetic energy of the particles, we can make the following observations:
1. **The gas particles outside the solar cooker** - Generally, air (gas particles) at ambient temperature will have lower kinetic energy than gas particles inside the cooker due to less heat exposure.
2. **The solid particles of the solar cooker walls** - While solids can have kinetic energy, their particles vibrate in place and are generally at a lower energy state compared to gas particles that are actively moving and colliding with one another.
3. **The gas particles inside the solar cooker** - These gas particles would have higher kinetic energy than those outside because they are heated by the black interior, which absorbs heat from sunlight.
4. **The gas particles inside the cook pot** - This is where the highest temperature would be reached due to direct exposure to heat from the black surfaces and the contained water, leading to even greater kinetic energy in the particles.
Putting this all together, the order from least to greatest average kinetic energy of the particles in each part is:
1. The gas particles outside the solar cooker
2. The solid particles of the solar cooker walls
3. The gas particles inside the solar cooker
4. The gas particles inside the cook pot
