Флашкарти: Foundations of Matter and Motion — 18 карти

Matter — properties?

Has mass, volume, and physical/chemical properties.

Matter — definition?

Occupies space, has mass, obeys conservation.

States of Matter — particles?

Solids (vibrate), liquids (slide), gases (move freely).

States of matter — characteristics?

Solid, liquid, gas; particle arrangement and movement.

Motion — formulas?

Speed = distance / time; acceleration = change in velocity / time.

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.
