Answer:

gaseous CO2 bubbles out of the solution

Explanation:

We already know that the dissolution of a gas in water is exothermic. Hence, when the temperature of a solution containing a gas is increased, the solubility of the gas decreases and the gas bubbles out of the solution.

Similarly, the dissolution of KNO3 in water is endothermic. This implies that the solubility of the solid increases with increasing temperature.

Thus the solid becomes more soluble at 75°.
