Is a rock getting melted into magma a chemical reaction?
No, the process of a rock melting into magma is a physical change, not a chemical reaction. The change is due to an increase in temperature causing the rock to undergo a phase change from solid to liquid.
Is magnesium physical change or chemical change?
Magnesium is not a change of any sort. It is a metallic element that can undergo both physical an chemical changes.
What are the changes do materials undergo in physical change?
In a physical change, materials undergo a change in their physical state or appearance without changing their chemical composition. This can include changes in shape, size, phase (solid, liquid, gas), or state (melting, freezing, evaporating). Physical changes are usually reversible.
What does undergo physical or chemical changes mean?
if during a change the chemical composition of the reactants change or any new products are formed then the reactant is said to undergo chemical change.if the state, color, phase or any other physical properties of the reactant change without any change the chemical composition of the reactants or formation of any new substances then it is said to undergo physical change
If you add hot coffee to cold milk is that a chemical or physical change?
Mixing hot coffee with cold milk is a physical change because the molecules of both substances do not undergo a chemical reaction. The temperature change occurs due to heat transfer from the coffee to the milk, but the chemical composition of the coffee and milk remains the same.
When do water undergo a change in physical properties?

How can a soda be a physical change?
A soda can undergo physical changes such as temperature changes causing condensation on the can, or changes in pressure leading to fizziness. These changes do not alter the chemical composition of the soda itself, making them physical changes.
