Thermal Phenomena in Dissolution of Salts

Observe the thermal phenomena occurring when 0.1 mol of the following salts is dissolved in 50 ml of water ammonium nitrate, anhydrous sodium sulphate, and sodium sulphate decahydrate (Glauber salt). For this purpose, pour 50 ml of water into a 100-ml beaker, measure its temperature, and, after pouring in the relevant amount of a salt, see how the temperature changes. Explain what occurs. 

Draw curves of the solubilities of the indicated salts. What relation can be noted between the heat of dissolution of a substance and the change in its solubility with the temperature
