Question

Grady is doing an experiment about the solubility of sugar. He puts 100 milliliters of water in each of three beakers. He leaves the first beaker at room temperature, heats the second beaker to 60°C, and heats the third beaker until the water boils at 100°C.
To the first beaker, he adds sugar, one spoonful at a time, until not all of the sugar can dissolve when he stirs it. He records the number spoonfuls that dissolved. Then he repeats the same process of adding sugar and stirring for the beakers of hot water and boiling water

Answer 1

Variables within an experiment many be altered in order to produce specific outcomes such as a reaction rate. The reaction rate is a measure of how fast a chemical reaction can happen. The increase in temperature increases the collision of molecules, such as the solid sugar solute and and the water molecules, which act as a solvent. Agitation, such as stirring, also increases the solubility by increasing collisions.

This continues until the solution becomes too saturated.
