The only physical factor that affects water balance is:

  1. pH

  2. temperature

  3. total alkalinity

  4. calcium hardness

The correct answer is: temperature

Water balance is a term used to describe the chemical makeup of pool or spa water. It is important to maintain proper water balance in order to ensure the safety and comfort of swimmers. The only physical factor that directly affects water balance is temperature. This is because temperature can affect the saturation levels of certain chemicals in the water, such as calcium and alkalinity. pH, total alkalinity, and calcium hardness are all chemical factors that can affect water balance, but they are not physical factors.
