Question 21 • AA-F26 Physical Science

Which would increase the rate of dissolving salt into water?

Answer
A
low temperature
B
little to no agitation
C
more surface area
D
darker colors

Explanation

Increasing the salt’s surface area exposes more of it to the water at once, so it dissolves faster. Low temperature and little agitation generally slow dissolving, while the water’s color does not affect the rate. The correct choice is more surface area.
