evaluating solutions\njosh is making homemade lollipops. the recipe calls for dissolving 400 g sugar in 100 g of water. his friend, alex, said that would never work because sugars solubility is 204 g per 100 g of water at 20°c. despite alexs doubts, josh successfully dissolves all 400 g of the sugar.\nwhat did josh do that allowed him to dissolve that much sugar in only 100 g of water?\njosh used sugar cubes instead of granulated sugar.\njosh used a pan with a large surface area.\njosh stirred the solution.\njosh heated the water.

Answer

Brief Explanations:

The solubility of sugar in water increases with temperature. Using sugar - cubes instead of granulated sugar, using a pan with a large surface area, or stirring the solution will not significantly increase the solubility limit to dissolve 400 g of sugar in 100 g of water at 20°C. Heating the water increases the solubility of sugar, allowing more sugar to dissolve.

Answer:

Josh heated the water.
