Question

Cindy left a small glass of salt water outside on her windowsill on a warm day. She remembered the glass a couple days later, but when she went to get it, she discovered that the water was gone and all that was left in the glass was a layer of salty residue. If the salt and water were well mixed when Cindy took the glass outside, how did this happen?

Answer 1

The particles settled and created a residue
