Find the odd one outa)Good absorbers are good radiatorsb)Shiny surface...
Explanation:
The odd one out is option C, "We wear dark-coloured clothes in summers."
The other options are related to the concept of heat absorption and radiation, while option C is about personal preference or cultural practice. Let's break down each option to understand why it is the odd one out:
A: Good absorbers are good radiators
- This statement is based on the principle of thermal radiation. Good absorbers of heat also tend to be good radiators of heat. This means that materials that can absorb heat well can also release it efficiently.
B: Shiny surfaces are good reflectors of heat
- Shiny surfaces have a high reflectivity, meaning they reflect a significant portion of the incident heat radiation instead of absorbing it. This property makes shiny surfaces good reflectors of heat.
C: We wear dark-coloured clothes in summers
- This statement is more subjective and based on personal preferences or cultural practices. While it is true that dark-colored clothes can absorb more heat from sunlight compared to light-colored clothes, it is not a universally followed practice in all regions or cultures.
D: Dark colors are good absorbers of heat
- This statement is true and aligns with the concept of heat absorption. Dark colors, such as black, absorb a larger amount of heat compared to lighter colors. This is because dark colors have a higher absorption coefficient for thermal radiation.
Therefore, option C stands out as it is not directly related to the scientific concept of heat absorption and radiation, unlike the other options.
