It is a physical change, as the nature of the sand remains the same, only its position is changed by wave action.
Adding antifreeze to your radiator is a physical change because the antifreeze retains its chemical composition and properties when mixed with the water in the radiator. It does not undergo a chemical reaction to form a new substance.
Adding sugar to cereal is a physical change because the sugar does not undergo a chemical reaction when mixed with the cereal. The sugar retains its chemical structure and properties, only altering the taste of the cereal.
No, adding hydrochloric acid (HCl) to magnesium (Mg) and observing the resulting chemical reaction is a chemical change, not a physical change. The reaction produces hydrogen gas and magnesium chloride, with new substances formed.
No, adding dish soap to water in a sink is not considered a chemical change. It is a physical change because the substances involved do not undergo a chemical reaction to form new substances.
Adding a base to an acid or vice versa in changing the chemical properties of that solution. In both cases you are neuralizing the solution. There might be a physical change as well, but it would depend on what chemicals where mixing. But this reaction will definitely have a chemical change.
Adding water (which is not a reactant) is a physical process.

Heating magnesium is a physical process.But the reaction of magnesium with oxygen at high temperature is a chemical process.
Adding salt to water is not a chemical reaction, nor is it a chemical change. When salt dissolves in water, this is an example of a physical change. Although the sodium and chlorine ions separate in the water, no chemical reaction takes place.

a physical reaction for the chemical structure is not changing.
Hi
It is a physical change.
In a chemical reaction something new is created. A chemical change is inreversible where as a physical change is. In a physical change nothing new is formed.
