Question

Read the excerpt from "Understand Wind Chill." The Wind Chill index is the temperature your body feels when the air temperature is combined with the wind speed. It is based on the rate of heat loss from exposed skin caused by the effects of wind and cold. As the speed of the wind increases, it can carry heat away from your body much more quickly, causing skin temperature to drop. What is the best summary of this excerpt?

Answer 1

The Wind Chill index is a measure of the perceived temperature due to the combination of wind speed and air temperature, conveying the heightened rate of heat loss from the body in windy conditions.

Step-by-step explanation:

The Wind Chill index reflects how cold the air feels on the skin based on the combined effect of air temperature and wind speed, emphasizing the increased rate of heat loss due to convection and wind. As wind speed increases, it removes heat from the body more efficiently, making it feel colder than the actual air temperature. This concept is clarified with an example, stating that a 15.0 m/s wind at 0°C feels as cold as still air at about -18°C. Insulating materials and the body's responses to cold are also discussed as means to mitigate heat loss.

Answer 2

The Wind Chill Index shows the loss of heat from the skin caused by the effects of cold wind.

Step-by-step explanation:

A summary is made when the text is rewritten with only the most important part of the original text. In this case, the abstract must be a smaller text and contain the information in a suppressed form, pointing only to the central and most relevant statements.

In this case, a good summary of the text shown in the question above is:"The Wind Chill Index shows the loss of heat from the skin caused by the effects of cold wind. "
