Anything that takes up space, has volume, density, and mass
Mass
how much matter is in an object
Weight
A measure of the force of gravity on an object
States of matter
liquid, solid, gas, plasma
liquid
water, juice, milk
solid
wood, ice, pencil
gas
oxygen and water vapor
plasma
lightning, sun, stars
intensive property
does NOT depend on how much matter is in an object to describe it
extensive property
DOES depends on how much matter is in an object in order to describe it
intensive property example
color, temperature
extensive property example
weight, length, mass
chemical property
indicates how a substance reacts with something else, matter will be changed into a new substance after the reaction
physical property
a characteristic that can be observed or measured without changing the identity of the substance
chemical properties examples
flammability, toxicity, reactivity
physical properties examples
color, smell, density, boiling point,
physical change
a change of matter from one form to another without a change in chemical properties
chemical change
A change that occurs when one or more substances change into new substances with different properties.
physical change examples
cutting string, crumpling paper, melting ice, evaporating water
Examples of chemical change
Rusting of iron nail, Baking a cake
Law of Conservation of Matter
matter cannot be created or destroyed
mass of reactants = mass of products
The reactants that went into the making of the product have the same mass as the actual product once its made since matter cannot be destroyed or created.
