To help keep buildings cool in the summer, dark colored window shades have been replaced by light colored shades. This is because light colored shades:
Correct answer: A. reflect more sunlight
- A. reflect more sunlight
- B. absorb more sunlight
- C. are more pleasing to the eye
- D. transmit more light
Explanation
Light-coloured shades have higher reflectivity, meaning they reflect a larger portion of incoming sunlight away from the building. This reduces the amount of solar energy absorbed by the building's interior

About Thermal Equilibrium and Heat
Thermal equilibrium means that bodies in contact have the same temperature and no net heat flows between them. The topic distinguishes heat from temperature, uses the zeroth law of thermodynamics, and covers heat transfer, specific heat capacity, thermal expansion and the conditions for reaching equilibrium.
