Solid carbon dioxide ('dry ice') and iodine ... solution where the concentration is the same everywhere in the solution. Diffusion in liquids is slower than diffusion in gases because the ...

from a liquid. For example, copper sulfate is soluble in water – its crystals dissolve in water to form copper sulfate solution. During evaporation, the water evaporates away leaving solid ...

Students will be able to use this model to develop an explanation for their observations of an M&M in a sugar solution. Dissolving a solid in a liquid depends on the interaction between the particles ...

When a solution evaporates, the water goes into the air but the ... The focus is that matter, whether solid, liquid, or gas, is made up of particles; that dissolving and evaporation happen at the ...
