Dissolving in water is a physical change.
Physical
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.
i think physical and chemical because for physical u r mixing it with the water. And for chemical I think it is because mixing drink mix with water is goes the effect the outcome chemical produced with both so it can also become a chemical change.....................
It is a physical change as you can change it back.
chemical
Carbonating water is a physical change because it involves dissolving carbon dioxide (gas) into the water to create carbonated water. No new substances are formed during the process, so it does not involve a chemical change.
its both a chemical change and a physical change.
An effervescent tablet dissolving in water is primarily a physical change, as the tablet breaks down into smaller particles and releases gas. However, if the reaction produces a gas (like carbon dioxide) due to a chemical reaction between the tablet's ingredients and water, it can also be considered a chemical change. Thus, it involves both physical and chemical changes.
Burning is a chemical change.
It is both a physical and chemical change.
both chemical and physical
