energy is absorbed
when the temperature gets higher and it gets hotter....
energy is released
when the temperature gets lower and it gets colder......
state of matter that doesn't have a definite shape or volume and particles are ionized
definite shape and volume, has the strongest attractive forces, particles vibrate in a fixed position, tightly packed particles with an ordered arrangement
change shape not volume, have a definite volume, not shape, particles slide past each other but stay close together
change shape and volume,weakest attractive forces, particles move at higher speeds than other 2 states

matter is made of atoms and molecules that act like tiny particles always in motion according to...
protons and electrons
the atomic # is also the...
