Is hammering gold until it becomes flat a physical change or chemical change?
Pounding a gold coin into a different shape would probably not effect a chemical change. If, however, the pounding produced enough heat to meal the coin, some chemical change could take place.
Is hammering metal into a flat sheet physical or chemical change?
A physical change means converting how an object looks or feels. Water changed into ice or water would be a physical change. Breaking, bending, melting, evaporating are all physical changes. A chemical change would be changing an object into something you can't change back. Taking bark off a tree (physical) and burning it is a chemical change. Chemical change means burning, rusting, and combustion. I hope this helped. Nossy
When soda goes flat is it a chemical or physical change?
When soda goes flat, it is primarily a physical change. The carbon dioxide gas that makes the soda fizzy escapes into the air, causing the bubbles to disappear. The composition of the soda remains the same, although its texture and taste may change.

Why fizzy pop going flat is not a chemical change?
The fizz is CO2 dissolved in the solution. This is then evoled as gas (this basically means makes bubbles) and is realsed into the atmosphere (comes out of the pop) Therefore it is not a chemical change as the CO2 was never chemically bonded to the pop soultion, just dissolved in it.
How long does it take for a beer to go flat?
There are many variables that contribute to a beer going flat (and by flat, we mean lose carbonation). If you pour it into a mixing bowl, it will go flat faster than if you leave it in the can or bottle because more of it is exposed to air. The type of beer is also a factor, as some contain more carbonation or are denser than others. According to opinions on the Internet, the time period ranges from 30 minutes to 48 hours for a beer to go flat.
Why would any one want flat beer?
Some people don't like the carbonation. And flat beer still has alcohol in it.
