Question
Which of the following will speed up the rate at which a solid dissolves in a liquid? A. crushing the solid B. shaking the mixture C. stirring the mixture D. all of these
Solution
D. all of these
Each of the options listed can speed up the rate at which a solid dissolves in a liquid.
A. Crushing the solid increases its surface area, allowing the liquid to come into contact with more of the solid at once, which speeds up the dissolving process.
B. Shaking the mixture helps distribute the solid particles throughout the liquid, which also speeds up the dissolving process.
C. Stirring the mixture, like shaking, helps distribute the solid particles throughout the liquid, speeding up the dissolving process.
So, all of these methods (crushing the solid, shaking the mixture, and stirring the mixture) can speed up the rate at which a solid dissolves in a liquid.
