A. The sugar melts.
B. The sugar loses mass.
C. The sugar turns into water molecules.
D. The sugar forms a mixture with the water.
E. The sugar can be separated from the water.
F. The sugar disappears and no longer exists.
G. The sugar molecules are spread among the water molecules.

I think c the suger molicules turn into water moliculs.
ReplyDeleteI think C the sugar tuns into water
ReplyDeleteBecause the suger desulves into the water and turns into the water molicules.
ReplyDeleteMent sugar molecules because when Dr. Coolidge put the sugar it dezolved.
ReplyDeleteI think it is G because the sugar can't really turn into water becasue it desolved
ReplyDeleteI think its C because if you put sugar in water and set it out the sugar dissolved.
ReplyDeleteGeorgia I disagree because the sugar dissolves in the water and turns into water molecules.
ReplyDeleteI disagree with seth because if you evporate the water the sugar will still be there. Only because sugar molicules can't turn into water molicules.
ReplyDeleteI agree with Georgia L. because sugar can't turn in to water like Georgia L. said. So I agree with Georgia L.
ReplyDeletei argreee with Georiga and Claire B because the sugar can't turn into water so i agree with Georiga and Claire B
ReplyDeleteI disagree with Georgia L, Claire B, and Cameron because the sugar stays in the glass and the sugar does not loose any mass so I think the answer is c
ReplyDeleteI mean lose not loose
ReplyDeleteI think it's D because the water mixes with sugar.
ReplyDeleteI think that it is D,E,and G.
ReplyDeletei think it is C because if u stir the sugar will get smaller and smaller and eventually turn into water.
ReplyDeleteI agree with Mary Ann... I think it is C because the sugar doesn't lose any mass
ReplyDeletei agree with melanie.....I think c becaus I think that the sugger promlem disolve into the water afer a store.
ReplyDeleteI think it is G because sugar can't dessolved and the water has allready dessolved.
ReplyDeleteI think it is G because the sugar dosent just dissapere
ReplyDeleteI think it is G because the sugar doesnt just dissapere
ReplyDeletei think its c because the water after a period of time disolves
ReplyDeleteI think I beacause it does'nt say to mix and if you mix it ot does'nt disaper it mix'es and makes a new substance.
ReplyDeleteI agree with georgia.L thet it is G. i think it is G because the water molicules disolve with the sugar molicules and it makes a solution then disolves
ReplyDeleteI think the answer is C because I have done that before and the sugar turns into water molecules.
ReplyDeleteI mean A,B,C,D,G,I.
ReplyDeleteI think its c because sugar can easily join other molecules but over time it can become part of the molecules its surround by
ReplyDeleteoops forgot the peried
ReplyDeleteI agree with Belynne. The suger does dissolve for sure. I dont think its posble for the water chemical to form a new subsence.
ReplyDeleteI think the answer is G because the sugar is at the bottom of the cup and if you just leave it out the sugar molecules dissolves but the water evaporates and the sugar is still there.
ReplyDeleteI think its C because the sugar desolves into to the water.
ReplyDeleteI agree with yaser because the sugar desolves into water
ReplyDeleteI agree with Mary Ann and Melanie because the sugar disolves into the water.
ReplyDeleteI think it's G because sugar can't physicaly break down and turn into water.
ReplyDeleteD & E. Because when you mix the water if it evaporates the sugar will still be in the cup and it is pretty easy to seporate.
ReplyDeleteI disagree with the answer c, becaue if you left the water out long enough it would evaporate and the sugar would still be in it's container
ReplyDeleteI think it is C, the water will turn into molecules.
ReplyDeleteI think it is c because the molecules have to go somewhere.
ReplyDeleteI think it is D.
ReplyDeleteI think it is E,and G. E because the sugar will sink to the bottom if you leave it out for a little bit. G because the volume of water in the glass is a lot more then the amount of sugar in a teaspoon so the sugar spreads out in the water
ReplyDeleteI agree with Crystal and other people who vote for C,the water will turn into molecules because it does not loose mass
ReplyDeleteSo yeah..........
ReplyDeleteI agree with D voters because like I said earlier c the sugar will disappear when the molecules will change. Now I think the sugar and the water molecules form a mixture. ☻
ReplyDeleteIs anyone there? :(
ReplyDeletekaion i desagree with u becuase the sugar is so small that it can just turn into the water molliculs
ReplyDeleteI think it is d because it is not just sugar or just wateer but it is sugar water.the water forms a mixture whith the water.
ReplyDeleteI think the answer c
ReplyDeleteI think the answer is c because, the sugar will desolve in the water and turn into water molecules.
ReplyDeletei don't think C is the right answer because the molecules of the sugar can't magically turn into water molecules. I think it is G because the sugar just doesn't float way they dissolve and spread among the molecules.
ReplyDeletei agree with you georgia because it makes mor since that the sugar would spread among the water molicules
ReplyDeletei do not, i think its we (sugar can be separated from water) because its true. if you let the water avaporate, you will find sugar left
