Considerations. Each chocolate-covered espresso bean contains 5 milligrams of caffeine, a stimulant that elevates your heart rate and blood pressure. Overconsumption of caffeine can lead to nausea, vomiting, tremors, restlessness and difficulty sleeping.
Summary. â¢ The pH value of a solution depends on the temperature. â¢ A pH value without a temperature value is meaningless. â¢ Solution temperature compensation converts measured pH to the pH at 25Â°C. â¢ Only pH values taken at the same temperature or converted using solution temperature compensation can be compared to each other.
Temperature Effects. The effect of temperature and pressure on a liquid can be described in terms of kinetic-molecular theory. The following figure illustrates the molecular behavior of a liquid at a low temperature near its freezing point and at a higher temperature near its boiling point.
