How could you prove that dissolving table salt in water is a physical change or not a chemical change?

well you know its not a chemical change when you see the salt dissolving because if your were to put something else like sugar then it would be a chemical change because the sugar would just float right to the bottom and stay there but salt would go around in the water and start dissolving.

Is dissolving salt in water a physical or chemical change and why how could you verify your answer?
physical change- solid to solution
How could you decide whether the dissolving of sugar in water is a physical or chemical change?
You can evaporate the water and recover the sugar unchanged. A chemical change means a chemical reaction has taken place and changed the substance chemically. A physical change means that a solid has become a liquid such as dissolving sugar.
Is burning a log a example of chemical or physical changes?
Although it has physical consequences, burning a log is a chemical change. The molecules of the log react with oxygen to form carbon dioxide, water steam, and many other products. A simple, fairly reliable test to tell the difference between physical and chemical changes is: Can the process be reversed rather easily? If the answer is yes, like dissolving salt in water, it is a physical change; if no, a chemical change.

Your sugar in water could not be seperated back out because it has dissolved into the water and now has different properties.
Is dissolving a solid a physical or chemical change?
it depends on if the solid is also water. if they are both water then its a physical reaction because it just changes the state of matter. if the solid isn't water then its chemical because the two substances then transform into one new substance.
Is it correct to say that dissolving a packet of juice powder in water makes a new substance such as fruit punch so it must not be a physical change?
The change is a physical one because the powder is simply dissolving into the water, and it could be powdered again by removing the water again. The physical properties of the fruit punch are very different, but not a chemical change unless there is a new substance created or precipitated.
