Burning of fuels is a chemical process.
No. State change is a physical reaction.
Correct, any phase change is considered to be a physical change.
Yes, whenever a substance changes its physical form without changing the chemical composition, it is considered a physical change. In this case, liquid butter turning hard does not become a different substance, so it is a physical change.
A solution turning cloudy is evidence of a chemical change.
Fire is not a physical or chemical property. Fire is not a property. Fire is a chemical reaction where oxygen combines with some or all of the chemical components of the fuel, emitting light and heat.
A physical and Chemical change.
It's not a physical change
Yes, evaporation is a physical change of phase.
No. State change is a physical reaction.
Correct, any phase change is considered to be a physical change.
This is a chemical change.
It is a chemical change. The wood, once burned, can't be restored to its original composition
Yes, whenever a substance changes its physical form without changing the chemical composition, it is considered a physical change. In this case, liquid butter turning hard does not become a different substance, so it is a physical change.
A solution turning cloudy is evidence of a chemical change.
water turning into ice
Assuming you mean liquid water turning into gaseous water, that is a physical change, because it's still water (H2O.)
