Physical Property
any property used to characterize matter and energy, and there interactions.
Example-color, density, electric charge, intensity
Chemical Property
Is a behavior or substance when it undergoes chemical change or reaction.
Example-heat or contribution, reactivity with water, electromagnetic force, ph
Example-heat or contribution, reactivity with water, electromagnetic force, ph
Physical Change
A change from one state (solid, liquid, or a gas) to another.
Examples- melt ice, breaking bottle, crumple paper, crush rock
Examples- melt ice, breaking bottle, crumple paper, crush rock
Chemical Change
Any processed determined by the atomic molicure composition.
Example- dissolve salt, burning wood, digest food, mixing acid and base
Example- dissolve salt, burning wood, digest food, mixing acid and base
Chemical Reaction
change in the molecule structure.
Example-change in color, bubbles, formation of crystals, evolution of heat
Example-change in color, bubbles, formation of crystals, evolution of heat
Law of Conservation of Mass
In a chemical reaction the mass of the products equals mass of reactants.
