It is a physical state change from a solid to a liquid. It is not a chemical change, unless other ingredients are then added when melted - as usually happens when used in cooking, for instance.
It is a physical change.
No, like all melting it is physical.
No. It is purely a physical change, that of melting. No chemical reaction takes place.
It is a physical change. There is no chemical reaction whatsoever.
Melting is a physical process; reaction with sodium is a chemical process.
A physical reaction is when no new substances are formed, there is a change of state eg ice melting to a liquid. A chemical change is when the reaction forms a new substance. eg gas bubbles. An acid reaction can be both. You need to look at the reaction taking place, look for change of state (physical) or any colour change or gas bubbles (chemical).
ice melting is a physical reaction
Yes. It's just like ice to water and back to ice. - - - - - "Reaction" implies a chemical change. Melting chocolate is a physical change. (Hardening melted chocolate can involve a whole series of physical changes but that's a different issue.)
Physical
it is certainly not a chemical reaction, and it is still melting something, so it is a physical reaction. it does depend HOW you melt it, but other than that, it is a physical reaction.
No, like all melting it is physical.
Melting of ice with salt is example of physical change as there is no chemical reaction involved .
No. It is purely a physical change, that of melting. No chemical reaction takes place.
No, it is a physical change, not a chemical reaction.
It is a physical change. There is no chemical reaction whatsoever.
Melting is a physical property because it only changes the physical state of the substance, such as wax, but does not change its physical or chemical properties. This is because melting is not a chemical reaction. Flammability, however, is a chemical property, and when a substance burns, that is a chemical reaction, and the physical and chemical properties of the products will be different than the reactants (starting substances).
