Is Alcohol vaporizing physical change or chemical change?
Alcohol vaporizing is a physical change because it does not involve a change in the chemical composition of the alcohol molecules. It is simply a phase change from liquid to gas.
Is evaporating alcohol a chemical change?
No. It is a physical change as the actual compound does not change, only its state does.
Is mixing salt and water chemical?
Mixing salt and water is a physical change, not a chemical change. The salt does not change its chemical composition when it dissolves in water, only its physical state.
Is boiling alcohol and then considering the vapor a chemical change?
Yes, boiling alcohol and considering the vapor is a physical change as it does not alter the chemical structure of the alcohol molecules. The alcohol vapor can be condensed back into liquid alcohol without undergoing a chemical change.
Is ethyl alcohol in a watch glass a physical or chemical change?
Evaporation of ethyl alcohol in a watch glass is a physical change, not a chemical change, because it does not alter the chemical composition of the alcohol. The process only involves a change in state from liquid to gas.

Is sugar dissolving in alcohol a chemical reaction?
No, sugar dissolving in alcohol is a physical process known as dissolution. In this process, the sugar molecules are dispersed in the alcohol molecules, but the chemical composition of both substances remains the same.
If sugar dissolves into hot milk is it a physical change?
no it is a chemical change
