Answer: Rain & temperature change :)
Explanation: Cause I said so
Rain and temperature changes cause the pH of the water to change.
Hence, options A and C are correct.
What is temperature?
Temperature is a physical quantity that expresses hot and cold or a measure of the average kinetic energy of the atoms or molecules in the system.
pH decreases with an increase in temperature. But this does not mean that water becomes more acidic at higher temperatures. A solution is considered acidic if there is an excess of hydrogen ions over hydroxide ions.
Rainfall dilutes pool chemistry levels and lowers the readings for pH, alkalinity, hardness, stabilizer, and chlorine.
Hence, options A and C are correct.
