kinetic molecular theory - atoms and molecules move faster when they are energized/heated

heat-the transfer of energy from one place to another

temperature - measurement of molecular movement conduction - heat through a solid medium

Conduction- heat threw a solid medium

radiation - hhat through space or air in all directions convection heat traveling vertically through air or liquid

Convection-heat traveling vertically through air or liquid

thermal contraction - increased heat causes slower movement of atoms/molecules which makes the object take up less space/volume

Thermal contraction- decreased heat causes slower movement of atoms/molecules

density - the, amount of matter(mass) in a specific space(volume). D=m/v
