During very cold weather conditions, cricket players prefer to wear white woolen sweaters rather than colored woolen sweaters. The reason is that white wool comparatively: 1. Absorbs less heat from the body 2. Emits less heat to the atmosphere Which of the above statements is/are correct? Correct Answer Both 1 and 2
Concept:
In the winter season, the body temperature is more than the atmosphere and as a result, radiation energy loss takes place.
Our body emits radiations in the infrared range and white color absorbs the infrared radiations.
Thus, fewer radiations are emitted than are absorbed and as a result, it keeps us warm.
