A nice breeze can cool you down on a hot day or send a chill through you on a day that is already cold. Wind carries heat away from our bodies making us feel cooler. This phenomenon is called wind chill. The wind chill temperature (sometimes called the wind chill factor) is the temperature we feel based on both the actual temperature and the wind speed.
In this experiment, the effect of wind on the temperature of a warm body will be measured and analyzed. A Temperature Probe will measure the temperature of warm water in a flask that represents a human body. A second Temperature Probe will measure the actual temperature of the air. There will be no wind in Part I, whereas wind will be generated by a fan in Part II.
In this experiment, you will
- Use a Temperature Probe to measure the effect of wind on the temperature of a warm body.
- Use a Temperature Probe to measure the effect of wind on the temperature of the air.
- Interpret your results.
