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.
Answer:
It transforms the electrical energy of the electrons into other forms of energy.
Explanation:
Just took the quiz
#8 positive kinetic energy
Answer:
1)the planet would need to have a source of energy that bacterial life can exploit, as well as a standing source of liquid water. At its surface, the temperature of Neptune dips down to 55 Kelvin. That's very cold, and there's no way liquid water could exist.
2)Neptune has the wildest and strangest weather in the entire Solar System. It has huge storms with extremely high winds. Its atmosphere has dark spots which come and go, and bright cirrus-like clouds which change rapidly. Neptune has an average temperature of -353 Fahrenheit (-214 Celsius).
3)To find life on Neptune, the planet would need to have a source of energy that bacterial life can exploit,
