Why does sugar dissolve faster in hot water compared to cold water?
Best Answer
I am going to have to respectfully disagree with Pranjal Rana.
The reason that sugar dissolves more quickly in hot water than in cold water has to do with the kinetic energy of the particles.
The faster (hotter) the water molecules are moving, the more energy they give to the sugar molecules when they collide with them.
Think about it this way: a sugar crystal is just a lot of sugar molecules stuck together. You dissolve the crystal you need to hit the molecules with enough force to break them off of the rest of the crystal.
