Flashcards: Fundamentals of Density and Particle Behavior — 10 cartões

Density — definition?

Mass per unit volume of a substance.

Density — definition?

Mass per unit volume, ρ = M/V.

Particle model — states?

Solids, liquids, gases differ in particle arrangement and movement.

SI units for density?

Kilograms per cubic meter (kg/m³).

Density measurement apparatus?

Ruler, displacement can, balances, Vernier callipers.

Displacement technique — purpose?

Measure irregular object volume via fluid displacement.

Particle model — purpose?

Explain states of matter and changes.

Solids — particle arrangement?

Particles tightly packed.

Latent heat — role?

Energy for state change without temperature change.

Internal energy — includes?

Kinetic and potential energy of particles.
