At the foot of a hill, the air temperature is . Take a fall of for each kilometre of height.
- What is the temperature at a height of km?
- What is the temperature at a height of km?
- What is the temperature at a height of km?
Need a reminder? The key ideaShow
Salinity is in parts per thousand, which is the grams of salt in each kilogram of water. Inland waters are below , the sea is to and some hypersaline lagoons are above . The air temperature falls about for each kilometre of height. A eurythermal organism bears a wide range of temperature, and a stenothermal one a narrow range.
The worked solution
Have you tried it?
Work it out on paper first. It is fine to get stuck or make a mistake: that is how we learn. When you are ready, go through the solution one step at a time, and check each step against your own.
Given. Start: . Fall: for each km.
Plan. Temperature height.
Step 1. (a) .
Step 2. (b) .
Step 3. (c) .
Answer: ; ; .
Check. The temperature falls as the height grows, as the lesson says.
What if? At about km the air reaches in this model.
Source. International Standard Atmosphere, a fall of 6.5 K for each km in the lowest 11 km.
