Question

6. You wish to investigate whether the rate of stirring a solid affects how fast it dissolves in water
Write a hypothesis for the investigation.
b. Identify the variable to change and the variables to keep constant to conduct a fair test​

Answer 1

Answer:

(6) Stirring a solute into a solvent speeds up the rate of dissolving because it helps distribute the solute particles throughout the solvent. For example, when you add sugar to iced tea and then stir the tea, the sugar will dissolve faster.

(B) An experiment usually has three kinds of variables: independent, dependent, and controlled. The independent variable is the one that is changed by the scientist. To insure a fair test, a good experiment has only one independent variable.
