Group of answer choices

Salt will not dissolve in water unless the water is stirred.

Stirring water increases the rate at which a salt dissolves.

Stirring has no effect on the rate at which a salt dissolves.

Stirring water decreases the rate at which a salt dissolves.

Answer 3

this is pretty simple. Read it, and make choices based on the evidence.

Answer 4

2. I would think the answer is obvious. You KNOW it can't be 1 because it does dissolve in 25 sec. You KNOW it can't be 3 because stirring at different speeds does have an effect. You KNOW it can't be 4 because faster speeds of stirring gives less time for the salt to dissolve.

Answer 5

stirring watter increases the rate at which a salt dissolves
