Hello!
The property that is being demonstrated when Janice was given a mixture of alcohol and water and her teacher told her that she could use temperature to separate these compounds is boiling.
The boiling point is the temperature when a substance goes from liquid state to gas state. If two liquid substances with different boiling points are in a mixture, they can be separated by heating one of them to its boiling point and condensing the gas in another container in a process called distillation. The difference in boiling points of alcohols (usually lower than water) and water allows to separate them in a mixture.
Have a nice day!
Water molecules pull the sodium and chloride ions apart, breaking the ionic bond that held them together. After the salt compounds are pulled apart, the sodium and chloride atoms are surrounded by water molecules, as this diagram shows. Once this happens, the salt is dissolved, resulting in a homogeneous solution.
hope this helps you
have a nice day:)
