# What's the air temperature when Δd=250m

• crystalspark
In summary, "Δd" refers to the change in elevation by 250 meters. Elevation and air temperature have an inverse relationship, with air temperature decreasing as elevation increases. The unit for air temperature is typically degrees Celsius or degrees Fahrenheit, but can also be measured in Kelvin. The accuracy of air temperature measurements at a change in elevation of 250 meters may vary slightly, but would not be significant. Air temperature can also be affected by factors such as humidity, sunlight, wind, and geographic location.

## Homework Statement

A hunter wanted to know the air temperature. The echo from a nearby cliff returned 1.5 s after he fired his riffle. If the cliff is 250 m away, how do you calculate the air temperature?

## Homework Equations

v=331 m/s + (0.59 m/s/c˚)T niSinθi=nRSinθR x=Δd/2 These eq'ns might be useful

## The Attempt at a Solution

x=250 m/2 = 125
v=125 m/1.5s = 83.33 m/s
83.33 m/s = 331 m/s + (0.59 m/s/c˚)T

why you used x = 125??

what is the distance traveled by sound wave in the whole process?

## 1. What does "Δd" mean in this context?

Δd refers to the change in distance, specifically the change in elevation. In this case, it is the change in elevation by 250 meters.

## 2. How does elevation affect air temperature?

Elevation and air temperature have an inverse relationship. As elevation increases, the air temperature decreases. This is because as altitude increases, the air becomes less dense and is therefore unable to hold as much heat.

## 3. Is there a specific unit for air temperature?

Yes, air temperature is typically measured in degrees Celsius (°C) or degrees Fahrenheit (°F). In scientific research, it is often measured in Kelvin (K).

## 4. How accurate is the air temperature when Δd=250m?

The accuracy of air temperature measurements depends on the equipment and methods used. However, in general, the temperature may vary slightly at different elevations, but the change in temperature for a change in elevation of 250 meters would not be significant.

## 5. Can air temperature be affected by other factors besides elevation?

Yes, air temperature can be affected by many factors including humidity, sunlight, wind, and geographic location. These factors can all impact the temperature at a specific elevation, so it is important to consider them when studying air temperature.
