Chemical X is a solid characterized by its white hue, which gives rise to sizable crystals. The chart provided illustrates the solubility of chemical X in water across varying temperatures.Jill 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 Jill change her method to dissolve all the X faster?

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

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

She could crush the X crystals into a fine powder before adding them to the water.
She could crush the X crystals into a fine powder before adding them to the water.

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

Answer 1

To dissolve all 30 grams of Chemical X faster, Jill should consider the method that increases the surface area of the crystals. Among the options provided, the best choice would be:

She could crush the X crystals into a fine powder before adding them to the water.

Crushing the crystals increases their surface area, allowing more water to come into contact with the solid and facilitating faster dissolution.
