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.
Effects of temperature. 1  physical properties of materials including the phase (solid, liquid, gaseous or plasma), density, solubility, vapor pressure, electrical conductivity. 2  rate and extent to which chemical reactions occur. 3  the amount and properties of thermal radiation emitted from the surface of an object.
