What are physical properties? �Mass - The amount of matter (stuff) in an object �Weight - the pull of gravity on an object’s mass
�Volume – the amount of space a sample of matter occupies �Solubility – the ability of one material to dissolve in another
�Density - The mass of a substance per volume (D=m/v)
States of Matter: �Solid –molecules are tightly packed and vibrate, has a definite shape �Liquid –molecules are loosely packed and move fluidly, takes shape of container and has a surface �Gas –molecules are not packed and move freely, no definite shape
States of Matter Solid Liquid Gas
Chemical Property �The ability or inability of a substance to combine with or change into one or more new substances �A characteristic of matter that you observe as it reacts with or changes into a different substance
What are chemical properties? �Flammability �Reactivity – ability to burn – ability to undergo a chemical reaction
�Ability to Oxidize – ability to rust �Toxicity – the degree to which a substance can damage an organism
