Chapter 20: Problem 19

The temperature at the cloud tops of Saturn is approximately 50. K. The atmosphere of Saturn produces tremendous winds; wind speeds of \(600 . \mathrm{km} / \mathrm{h}\) have been inferred from spacecraft measurements. Can the wind chill factor on Saturn produce a temperature at (or below) absolute zero? How, or why not?

Short Answer

Expert verified
Answer: No, the wind chill factor on Saturn cannot make the temperature reach absolute zero, as wind chill only affects the perceived temperature experienced by living organisms exposed to such conditions and does not change the actual atmospheric temperature.

Step by step solution

01

Understanding Wind Chill

Wind chill is the perceived decrease in air temperature caused by the cold wind blowing on a body. It is a measure of how cold the wind can make someone feel under certain conditions. The concept of wind chill applies only to animals and humans, as it measures heat loss from exposed skin due to wind and cold. However, it does not affect the actual atmospheric temperature.
02

Temperature Reduction due to Wind Chill

The wind chill formula calculates the "felt" temperature resulting from the heat loss, not the temperature reduction. It means the temperature in Saturn's atmosphere remains the 50 K, no matter how strong the winds are.
03

Can Wind Chill Make the Temperature Reach Absolute Zero?

As mentioned earlier, wind chill is not an actual decrease in temperature, but rather an interpretation of how the cold wind feels on the exposed skin of humans and animals. This means that wind chill cannot make the temperature of Saturn's atmosphere reach absolute zero.
04

Conclusion

Based on the understanding of wind chill and its effects, it is not possible for the wind chill factor on Saturn to produce a temperature at (or below) absolute zero. The actual temperature in Saturn's atmosphere remains unchanged regardless of the wind speeds, and wind chill only affects the perceived temperature experienced by living organisms exposed to such conditions.
