Presentation transcript:

Identify and describe various processes used to separate mixtures. Will it take longer for a sugar cube to dissolve in hot water or cold water?? Why?

A sugar cube will dissolve quicker in HOT water because the molecules in hot water have more energy & are moving faster so they are hitting the sugar cube harder.
