If its 3C outside with a windchill factor of -8C, will water freeze due to the windchill factor?
No. The freezing point of pure water is, as you know, 0C. If the air temperature is not at or below freezing there is no way that any matter in contact with the air can fall below freezing. This is the first law of thermodynamics, and applies to all objects, liquid, solid or even a gas that is contained in a way so as not to mix with the air. Water placed in a room at 3C cannot get colder than 3C no matter what the wind is doing. In fact, even if the wind is howling and the water is already frozen as ice, if the temperature is 3C the ice will melt and warm to 3C in time. The reason people and warm blooded animals feel a windchill is that we generate heat internally as we metabolize food and fat. When the wind is blowing and the temperatures are cold enough (as opposed to a hot summer day) our bodies lose this internally generated heat as the air flowing around us carries the heat away. The stronger the wind, the faster this heat loss occurs and the more we “feel” the cold. Heat is a fo
No. The freezing point of pure water is, as you know, 0C. If the air temperature is not at or below this temperature, the water temperature will also remain above freezing and the water will not freeze. Water in an environment where the air is at 3C cannot get colder than 3C no matter what the wind is doing. In fact, even if the wind is howling and the water is already frozen the ice will melt and the water will warm to 3C over time. The reason people and other warm blooded animals feel colder due to the wind is that we generate heat internally as we metabolize food and fat. When the wind is blowing and the temperatures are cold enough (as opposed to a hot summer day) our bodies lose this internally-generated heat as the air flowing around us carries the heat away. At a given temperature, the stronger the wind is the faster this heat loss occurs and the colder we feel. The wind does not actually make the air colder so it can not cause water to freeze if the temperature is above 0C.
