Physical and Chemical Properties


         Flammability : chemical properties,because A chemical change is eternal by producing a new substance. A chemical change is called a chemical reaction
          The logs for example we take and burned, the wooden rod turned into ash, smoke and accompanied by the release of heat. Ash, smoke and heat coming out is not changed back to wood sticks

Taste : physical properties, Example The nature of sugar dissolved in water such a sweet taste still remains visible if the sugar solution evaporated. be recovered sugar with the same sweet nature
Fermentation of cassava to produce tape : Chemical properties,because cassava is alredy a tape cant be returned to cassava again
Color : It depends. In most cases, it is a physical change why? because if mixed would change only its form alone, while the composition is not changed
Smell :the smell is a physical change because no reaction
Solidity : physical properties,because it can be see and can be felt
Vaporization of water :physical properties,because can be seen when the water turns to steam,and steam can’t
          be returned to the water again.
Breakble : physical properties,because of that  broke out items aren’t able to return
         to normal
