Assignment:
It is the middle of winter and the weatherman forecasts a cold, overcast, but dry day, with an average temperatures of -2 degrees Celsius. However, he highlights the presence of a strong wind with a wind chill factor that will make it feel like -10 degrees Celsius. What is meant by the term 'wind chill'? How can it be quantified? Discuss its physical origins and assumptions. If a person stands in the middle of a field and holds a thermometer up to the wind for five minutes, what temperature will it read?
