A large bar of solid gold is melted into liquid. The liquid is then poured into molds to make a number of gold coins. Was this a chemical or physical
change? Explain.

Chemical, because the gold turned into something new and is no longer gold.

Physical, because the gold changed size and shape, but is still gold.

It is physical, the gold is still gold and there has not been any chemical change. Melting, boiling, freezing, etc. are physical changes.

the "dirty dozen" chemicals banned in an international treaty are formally known as persistent organic pollutants, or pops. the united nations environment program provided this background on what they are and what they can do to humans and wildlife.
