Chemical property
<--- flammability Chemical property's are characteristics you observe when a substance interacts with another substance
Ex rusting,flammability,reactivity with other chemicals,toxicity and radioactivity
Physical changes
A physical change is a change that alters the form or appearance of a substance but does not change the substance
Ex:freezing point,mass,color,boiling point,Length,odor
Chemical changes
