States of matter X atoms elements and compounds Flashcards
Describe arrangement, movement, energy, density of particles in a solid?
Regular arrangement
Vibrate in fixed position
Low energy
High densities
Describe arrangement, movement, energy, density of particles in a solid?
Random arrangement
Particles slide past each other
medium/greater energy
Medium density
Describe arrangement, movement, energy, density of particles in a solid?
Random arrangement
move quickly in all directions
high energy
low densities
Explain melting?
It is when a solid changes to a gas
The attractive forces/bonds are weakened
Occurs at a specific temperature called freezing point
Explain boiling?
It is when a liquid turns into a gas
It only occurs at the boiling point
Boiling happens throughout the liquid
Bonds/attractive forces are broken
Explain freezing?
It is when a liquid turns into a solid
Bonds/attractive forces are strengthened
It occurs at the freezing point (same as melting point)
Explain evaporation?
It is when a liquid turns into a gas
Bonds are broken
Evaporation only occurs at the surface
It can occur over a range of temperatures
Explain condensation?
It is when a gas turns into a liquid
It can occur at a range of temperatures
Bonds are formed
Explain sublimation?
It is when a solid turns directly into a gas without going through the liquid state
