The surface areas of four solutes are 2 mm2, 6 mm2, 10 mm2, and 4 mm2. which solute will dissolve the quickest?
a. 2 mm2
b. 4 mm2
c. 6 mm2
d. 10 mm2

I believe the answer is: d. 10 mm2

To dissolve, the molecule of the solute need to contact the with the solvent. Assuming the solute is drown completely. the area of contact with the solvent will be same as the solute surface area. Higher surface area will make the solute dissolved with higher speed. Multiple object with smaller size are known to have more surface area that single object with bigger size.

you didn't give any options but heres what i can tell you: an inference is likely to change based on additional observations. the latter is something that you have seen or sensed using your sensory organs while the former is like a conclusion out from what you have observed.

all these collisions do one thing, and that thing is explained in the last option. when dusst, rocks and ice collide, they harden and form giant layers of rocks or hard ice.

d)   to harden materials to form different parts of earth’s layers

hope it ,
