Question

If you accidentally left a cup of Kool-aid outside and most of the water evaporated, how will the concentration of the solution change?

A. The concentration of the solution will increase because the water evporated; the leftover solution has the same amount of sugar and Kool-mix but with a smaller volume of water.

B. The concentration of the solution will decrease because the water evporated; the leftover solution has the same amount of sugar and Kool-mix but with a smaller volume of water.

C. The concentration will stay the same because as the water evaporates the sugar and Kool-aid mix also evaporate.

D. You would have to measure the concentration in a lab

Answer 1

A.

Step-by-step explanation:

Since there is less water and the same amount of kool aid (since the water would evaporate but the kool aid wouldn't), this means that there is a higher concentration of kool aid is a smaller amount of water.
