Answer:

Explanation:
The pH scale stands for the power or potential of hydrogen. It measures how acidic or basic a solution based on the concentration of hydrogen ions and a scale from 1 to 14.
This scale is unique because it is logarithmic. So, every time the pH changes by 1 on the scale, the actual concentration of the solution increases or decreases by a tenfold.
So, a solution with a pH of 7 is ten times more acidic than a solution with a pH of 8. This can be translated to:

The black coffee has a pH of 5 and the hand soap has a pH of 10. We want to find how many times more acidic coffee is, so we subtract 5 from 10 and get 5. The difference in pH is 5.

Coffee is <u>10⁵ or 100,000 times more acidic than hand soap.</u>
Answer:
The difference in altitude between these two regions.
Explanation:
As you can see in the question above, Lüderitz and Santos are two regions that are the same distance from the equator, which indicates that the two regions have the same latitude and are in tropical zones. In addition, the two regions are close to the ocean, but the air in Lüderitz is cooler.
This indicates that there is a difference in altitude in these regions and Lüderitz has a higher altitude than Santos, which is why Lüderitz's air is colder and Santos's is hotter.
Altitude is a geographic term that represents the distance of a region in relation to the level of the sea. The higher the altitude, the greater the distance.
The higher the altitude of a region, the colder its air will be. This is because in high altitude regions, air is thin and has a small capacity to retain heat.
