I thank it is a electricity and something like that
Nonexamples are instances or cases that do not fit a particular concept or category. For instance, if the concept is "birds," a nonexample would be a cat, as it does not possess the characteristics of a bird. Similarly, if discussing "fruits," a nonexample could be a potato, since it is a vegetable and not classified as a fruit. Nonexamples help clarify and reinforce understanding of what a concept is by highlighting what it is not.
Freezing of water is a physical change.
bone,
Do the logs change from wood to some other substance? No, so it has to be a physical change.
circle, sphere, oval
non example of chemical change: one non example is ice. ice is NOT an example of chemical change.
Color Speed Sound
It's a physical change why are some people f$#@%ing stupid and saying a chemical change??
is a physical change. The popsicle is still a popsicle even if its freezed, nothing has changed with it but its physical appearance :)
they are both some sort of change
Nonexamples of melting point include processes such as boiling, which involves the transition of a substance from liquid to gas at its boiling point, and sublimation, where a solid transforms directly into a gas without passing through the liquid phase. Additionally, chemical reactions that result in the formation of new substances do not relate to melting point, as they involve changes in chemical composition rather than physical state. Other nonexamples are freezing, which is the transition from liquid to solid, and evaporation, where liquid turns into gas at temperatures below boiling.
