No
No not ia any way
Something that burns or is flammable would be a chemical change.
No, that would probably be considered a physical change. It is only a chemical reaction its chemical makeup is changed.
Freezing a snow man is physical change because you are not changing the chemical formulae of the snow because it's just frozen water crystals packed together to make a snow man. It's also reversible to it's original from (water). For a chemical change the formulae of the substance has changed once you have made the change (e.g baking a cake). Its also irreversible, because you cant make a cake back in flour, egg, sugar, butter, etc. -Hope this was useful
I would think it to be a Physical Change. Not chemical.
No, corrosion is a chemical change of the metal involved.
The egg actually turns solid inside, so that is a physical change. If the egg turned into a liquid or gas after boiling it then that would be considered "chemical change"
Dissolution doesn't involve the chemical transformation of the salt.

Chocolate syrup being a thick liquid is a physical change, as the state of matter is altered but the chemical composition remains the same. If the chocolate syrup were to change in composition, for example by caramelizing or burning, it would be considered a chemical change.
Mixing boron and vanadium together physically is not a chemical change because the substances retain their original properties. However, if a chemical reaction occurs between the two elements, resulting in the formation of new compounds, then it would be considered a chemical change.
Mixing Epsom salt and ammonia would result in a physical change. It is considered physical because no new substances are formed during the mixing process.
