This is sorta awkward. Gold doesn't really "burn" in the general sense. Take some solid gold and heat it. When it gets hot enough (1064.18 °C or 1947.52 °F), it melts. It was a solid, and now the gold has changed state to become a liquid. But here's the catch. Gold, which is called a noble metal, just sits there molten. That's because it doesn't like to react with anything, and that means it is extremely difficult to "burn" gold. It won't oxidize (combine with oxygen), which is the basis for most "burning" in the conventional sense. (There are other forms of burning, but we'll set them aside for now.) Our liquid gold? Continue heating it and it will change state to a gas and boil away. Just like water would. The term "burning" doesn't really represent a change of state. A change of state is a transition from solid to liquid to gas to plasma or back the other way. (Yes, some things change from solid directly to a gas and such, but let's look at the basics.) If we take ice and heat it, it melts. Keep heating it and it changes to steam. But it is still water. That's the key to change of state. In a change of state you don't chemically change the "stuff" you are heating or cooling - like the water we spoke about. When we "burn" something, chemical reactions take place, and the original chemical elements and compounds involved are changed by rearrangement. Gasoline is composed of a bunch of different hydrocarbons. If we burn it completely in air (with oxygen), the end products are water and carbon dioxide. (Set aside the other combustion byproducts that occur at elevated temperatures and pressures and that appear with incomplete combustion.) Burning liquid gasoline does not change its state but changes its chemistry. So burning something really doesn't represent a change of state. Gold is an interesting metal and an interesting chemical element. A link is provided to the Wikipedia article on gold in case you want to do some additional reading. The pics alone are worth Surfing on over for.

Gold is a solid at 25 degrees.
Change of state of a substance is a physical property!
Matter changing state is usually a result of the material changing temperature and/or a change in the surrounded pressure on the material. The change of state is usually associated with a change in its density.
It is a physical change (melting).
The word for this particular state change is "sublimation".
Melting of gold for jewellery making is a physical change as no new substance is formed after melting. Changes in state or phase are physical changes.
Yes gold melts to liquid gold at 1063C and boyls to gaseous gold at 2600C
The burned tower is in the northwest part of Ecruteak city.
Forming a bar of gold into wire is a physical change, not a chemical change. In this process, the gold undergoes a change in shape and physical state, but its chemical composition remains unchanged.
No, it was burned in Gold and Silver as well.

The Burned Tower is not in Pokémon Emerald. It is found in the Generation II games (Gold, Silver, and Crystal) and their remakes (Heart Gold and Soul Silver).

It received a massive influx of immigrants.
There is no " city of California". We have a state of CA with many cities.
physical: it's a change of state, it does not change the chemical makeup: molecular, atomic
