My science final. Making my own lab. (help) Answered
Ok so my science final is to make our own lab involving those little sponge capsules that turn into animals when put in water. I understand that hotter water will dissolve the capsule faster because the molecules are moving much faster and are hitting the solute more. Each student gets 4 capsules to use, so I will have room temperature water, boiling, and ice water and the water temperature recommended on the back of the capsules box (50-60 c. which is 122-140 f) . My question is which one is my control? I have figured that it would either be the room temperature water or the recommended water, but which and why?
