Chemical X is a solid with white color that forms large crystals. The solubility of chemical X in water at different temperatures is shown to the left. Irina wants to dissolve 30 grams of X in 1 liter of water. She does so by stirring 30 grams of the large crystals into 1 liter of water at 45°C. How could Irina change her method to dissolve all the X faster?

She could reduce the temperature of the water to 35°C.

She could increase the temperature of the water to 55°C.

She could add the X crystals to the water but refrain from stirring them.
