states of matter Flashcards
What are two propeties of soilds
fixed in shape and volume
What are two properties of liquids
Shape changes to fit container and fixed in volume
What are two properties of gasses
Shape and volume change to fit container and can flow and easily compressed
Describe soild partivles
packed closely together particle vibrate but can’t move around
describe liquid patricles particles
particles are close but can move around
describe gas particles
Particles spread far apart and move randomly in all directions
What is melting
is when soild goes to liquid
what happens to the particles during melting
The particles vibrate ad move until they have enough energy to move around
What is freezing
the opposite of melting , liquid solidifies and stops being able to flow , the solid will take its shape in the container it froze in
What happens to the particles during freezing
Particles lose energy so move around less and less till they can’t move and only vibrate
What happens to the particles in boiling
Particles move as they gain energy until eventually they break away from the liquid
What is condesning
Gas changes into liquid as it cools
What happens in particles during condensation
Particles move slowly and get closer together as they lose energy until they no longer spread out
What is subliming
Soild turns straight to gas
What happens to the particles during sublimation
particles are packed together until they gain enough energy to move around and spread apart
