States of Matter (Leaving Cert Engineering): Flashcards

Solid, liquid, and gas

Rigid lattice; particles vibrate in fixed positions

Incompressible, fixed shape & volume, high density

Take container shape, fixed volume, slightly compressible

Fill all space, highly compressible, no fixed shape/volume

All particles are in constant motion

$-273.15°C$ or $0$ Kelvin

Solid changes to liquid (energy added)

Solid changes directly to gas (energy added)

A mixture formed when solute dissolves in solvent

Mass of solute that dissolves in solvent at set temp/pressure

Larger particles held up by collisions, will settle out

Solutions dissolve completely; suspensions settle out

Separates liquids by different boiling points

Charged particles that have gained or lost electrons
