A sample of an ionic compound is dissolved in water and the water gets warmer. What is acting as the system? What is acting as the surroundings? Does heat flow from the system to the surroundings or from the surroundings to the system? Is dissolving this salt endothermic or exothermic? What is the sign of enthalpy for this process?
