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.
Changing the temperature of something does not change its weight.
The change from a solid to a liquid is a physical change, as the substance's chemical composition remains the same. Physical changes affect the state or form of matter without altering its chemical composition.
Yes, shaping a gold bar is an example of a physical change because the gold is not chemically altered during the process. Only its physical appearance and shape change.
Gold's physical state at room temperature is solid. That's one of the reasons why gold is widely used to make various jewelry pieces.

No, gold does not change colors when burned. When heated, gold may maintain its appearance or form an oxide layer on the surface that can be rubbed off to reveal the original color. Burning gold may release fumes and emit a metallic smell, but the metal itself does not change color.
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
Yes. Gold would have to bond with something for it to be a chemical change.
Burning gold will not help determine if it is real or not, as gold's properties do not change when burned. To determine if gold is real, it is best to conduct a professional assay test or have it evaluated by a reputable jeweler.
When a gold necklace is burned, it can result in the formation of black soot due to the impurities present in the gold or the materials used in making the necklace. However, genuine gold does not change its chemical properties when burned and will not turn black.
Pouring molten gold in a mold is a physical change because it involves a change in state from liquid to solid without altering the chemical composition of the gold.
The burned tower is in the northwest part of Ecruteak city.
No, real gold does not turn black when you burn it. When heated, gold will retain its color and may become softer or deform, but it will not change color like other metals that oxidize when burned.
No, it was burned in Gold and Silver as well.
The change from solid gold to liquid gold is a physical change because it does not alter the chemical composition of the gold. The transition from solid to liquid is a result of a change in temperature and does not involve any chemical reactions.
