P3- Particle Model Of Matter [1] Flashcards
What do colliding particles create
Pressure
Describe solid particles
Ordered and compact and they vibrate around a fixed point
Describe liquid particles
Together but can move past each other move with random direction and speed
Describe gas particles
They have the most energy and move with random direction and speeds
What is density
The compactness of a substance
What can is used to measure irregular object’s volume
A eureka can
What type of energy do particles have
Kinetic energy
Why do states change with increased temperature
Because the energy is converted to kinetic and that allows them to break the bonds holding them together
What is the name for when a solid directly turns into a liquid
Sublimation
What is the name when a gas turns to a liquid
Condensation
What is the name when a liquid turns into a gas
Evaporation
What is the name when a solid turns into a liquid
Melting
What is the name when a liquid turns into a solid
Freezing
During a change of state do the number of particles Change
No just the arrangement
