A. Relates body heat loss with wind to an equivalent temperature with no wind
B. Indicates the temperature at which water freezes on exposed skin
C. Takes into account humidity and air temperature in expressing the current air temperature
D. Tells farmers when to protect crops from a freeze
✅ The correct answer is option A.
Wind-chill or windchill is the lowering of body temperature due to the passing-flow of lower-temperature air. Wind chill numbers are always lower than the air temperature for values where the formula is valid. When the apparent temperature is higher than the air temperature, the heat index is used instead.
