the students have decided to test how removing the reflective lid will affect the efficiency of the solar cooker. explain how this change will impact the transfer of thermal energy in the solar cooker design and describe one possible design improvement the students can make to compensate for this change.
Answer
Brief Explanations:
The reflective lid on a solar - cooker reflects and focuses sunlight onto the cooking area, increasing the amount of solar energy absorbed and thus the thermal energy. Removing it will reduce the amount of sunlight reaching the cooking area, decreasing thermal energy and efficiency. To compensate, students could increase the surface area of the solar - collecting material or use a more efficient solar - absorbing material.
Answer:
Removing the reflective lid will decrease the amount of sunlight reaching the cooking area, reducing thermal energy and efficiency. A possible design improvement is to increase the surface area of the solar - collecting material.
