In chemistry, pH is a measurement of how acidic or basic a substance is. The pH of pure water is affected by the temperature of the water. The following table shows some values of f(t), the pH of water at temperature t (in degrees Celsius)
Temperature t(celsius) pH f(t)
10 7.5
20 7.09
30 6.93
40 6.77
50 6.61
Which of the following is the most accurate interpretation of the data in this table
