Sergio wanted to find out if changing the temperature of a solution changed how quickly salt dissolved in it. First, he tested a control solution at room temperature, or 25 °C, and measured how fast salt dissolved in the solution. Next, he cooled solution A to 10 °C and heated solution B to 40 °C and added salt to each. How quickly did the salt dissolve in solutions A and B compared to the control solution?
A faster for both solution A and solution B
B faster for solution A and slower for solution B
C slower for solution A and faster for solution B
D slower for both solution A and solution B
C
