A question that can help you determine if silver underwent a chemical or psychic change is

1. is/has the substance changed? is it still the same or is it something completely new?
. if it is the same then its physical but if its not the same then its chemical.

.(ex:) if you cut up and paper into pieces then the substance hasn't changed because its still paper, just smaller xD this would be considered a psychic change.

.(ex:) if you burn a paper then the substance has change because its no longer paper/you can no longer write on it- this would be a chemical change.

another question would be

2. is it reversible? or not? (reversible- physical change) (not reversible - chemical change).

i hope that this kind of helps you.. xD sorry that its really long.

Answer:

Solid turns to liquid.

Explanation:

When you freeze water, it turns into ice. When melted it's still water. No chemical changes were made to the piece of ice melted. The only change was ice (solid) to water (liquid)

Conservation of Matter - Matter can change forms through physical and chemical changes, but no matter what, matter is conserved. The same amount of matter exists before and after the change.
