a change in state of matter

the amount of matter in a substance

the amount of space an object takes up

a change in chemical properties

a change in density

a change in one or more physical properties

a decrease in volume of a substance due to pressure applied to that substance

an increase in volume of a substance due to pressure applied to that substance

when the volume of a substance is equal to the pressure applied to that substance

the measure of how much matter is in a unit of volume

mass x volume - density

the smallest building block of matter

occurs when volume increases

occurs as volume increase from heat

occurs when one type of matter spreads evenly through another

when matter is broken down into smaller pieces (into a liquid)

when matter changes state

when a chemical reaction occurs

when mass decreases because of heat transfer

when volume of a substance is increased by adding energy in the form of heat

when a physical change occurs which causes diffusion

the smallest building block of nature

the amount of space taken up by an object

is what things in the Universe are made of

the amount of space taken up by matter

that amount of space taken up by energy

the amount of space taken up by waves

a positively charged particle in the nucleus

a negatively charged particle in the nucleus

the smallest building block of all matter

are made up of two or more atoms bonded together

the smallest building block of all matter

include one proton, one neutron, and one electron

a phase of matter with very low energy

a phase of matter with extremely high energy

a phase of matter where the atoms are not moving and fixed in place

a neutral charged particle in the nucleus of the atom

a positive charged particle in the nucleus of the atom

a negative charged particle flying around the outside of the atom's nucleus

a neutral charged particle in the nucleus of an atom

a positive charged particle in the nucleus of an atom

a negative charged particle flying around the atom's nucleus
