I NEED HELP PLEASE, THANKS~ :)

Describe what happens when a small amount of NaCl is added to a cup of water. How does diffusion work at the molecular scale? What would happen if the same amount of NaCl were added to a cup of cold water and a cup of hot water at the same time?

See explanation

Explanation:

On a molecular scale, when you drop a small amount of NaCl or table salt into water, the molecules of salt break apart from each other and diffuse into the liquid because they are attracted to it more strongly. When the water is hot, the molecules diffuse more quickly, because the water molecules move faster and attract the salt molecules faster.

Hope this helps!
