Answer:
Based on the experiment described, the black can could absorb more radiation and ended up hotter than the silver can. This is due to the difference in their ability to absorb and reflect light.
Step-by-step explanation:
The black can absorbed more light because it has a high absorbance coefficient for visible light, meaning it can absorb a greater amount of photons than the silver can. On the other hand, the silver can has a high reflectance coefficient for visible light, meaning it can reflect a greater amount of photons.
When the heating lamp was placed over both cans, the black can absorb more photons of the light, and therefore absorbed more energy. This increase in energy leads to an increase in temperature, while the silver can reflected more photons, absorbing less energy and resulting in a lower temperature. This is supported by the observation that the black can ended up getting hotter.
