The density increases as the mass of the solution increases but its volume remains the same.
A match burning is a chemical change. Salt dissolving in water is a physical change.
Dissolving salt in water is a physical change- no chemical reaction took place. If the water evaporates, the salt is still there.
Yes, salt dissolving in water is a physical change because it does not involve a change in the chemical composition of the salt. The salt molecules are simply dispersed in the water, but they remain the same chemical substance.
Salt dissolving in water is a chemical change, the white residue is left when the water gets saturated by the salt and the salt starts to come out of solution to gain equilibrium. The residue can also be left behind when boiling off the water.
Dissolving tablets is a physical change, as they can be distilled out again.
Dissolving Skittles in salt and water is a physical change. The Skittles are still the same chemical compounds, but they are now dispersed throughout the water-salt solution.
Dissolving is a physical process.
No. It is a physical change.
Dissolving in water is a physical change.
Dissolving in water is a physical change.
Dissolving in water is a physical change.
Dissolving salt in water is an example of a physical change. Although the ions of sodium and chlorine separate when the salt dissolves, no chemical reaction takes place.
