The reaction H2O <-----> H+ + OH- is endothermic, so it will move to the right when the temperature is raised. This makes more H+ ions (and more OH- ions). So the pH of perfectly neautral boiling water is less than 7, because there are more H+ ions than there were at room temperature.

when a temperature is high, the pH, or chemical reaction speeds up too. if the temp is low, the pH slows down
