Answer:
The pH meter has a scale on the screen that measures the pH value from 0 to 14 for a given solution. It works on the principle of comparing voltages reading. When the electrode is dipped into the solution, the voltage produced by the ions of the solution is send to pH meter that compares the reading to the known voltage value of a standard solution. The reading is then displayed on the meter. The measures of precise Potential Difference values plays an important role in pH measurements.

Explanation:
The three major difference between Pluto and the other Terrestrial planets are
1. Pluto's orbit is far from being circular. Its orbit has highest eccentricity,meaning that its distance from sun varies more than any other planet of the solar system.
2. The ratio of the size of the planet to size of moon is highest for the for Pluto. its moon Cheron is quite large which is surprising as Pluto gravitational force is not much.
3.Pluto's orbit is the most tilted orbit of the solar system.
The Answer Is B (: because if it was closed no light could get throw and its not d because air doesnt circulate throw water xD HOPE THIS HELPS ANSWER IS REALLY B ♥
