Matter — properties?
Has mass, volume, and physical/chemical properties.
States of Matter — particles?
Solids (vibrate), liquids (slide), gases (move freely).
Motion — formulas?
Speed = distance / time; acceleration = change in velocity / time.
Matter — definition?
Occupies space, has mass, obeys conservation.
States of matter — characteristics?
Solid, liquid, gas; particle arrangement and movement.
Density — what is?
Mass per unit volume.
Physical vs chemical properties?
Physical: color, melting point; Chemical: reactivity.
Phase changes — examples?
Melting, freezing, vaporization, condensation, sublimation, deposition.
Gas law equation?
PV = nRT.
Motion quantities?
Distance, displacement, speed, velocity, acceleration.
Graph slope indicates?
Speed; flat line = no movement.
Separation techniques?
Filtration, distillation.
Physical vs chemical reactions?
Energy transfer, phase change vs chemical change.
Atoms — role?
Basic units of elements.
Elements — definition?
Pure substances with one type of atom.
Compounds — composition?
Chemical combinations of elements.
Mixtures — types?
Homogeneous or heterogeneous.
Particles in matter?
Atoms, molecules, ions.
