States Of Matter Flashcards
What is the movement of solid particles?
They vibrate in fixed positions
What is the arrangement for liquid particles?
Random (the have no pattern) they are close together
What is the movement of liquid particles?
They move around each other
What is the arrangement for gas particles?
Random (they have no pattern) they are far apart from each other
What is the movement of gas particles!
They move fast in all directions
What is sublimation?
A solid turning into a gas (no liquid state)
What arrangements are solid particles in?
Regular (in uniform) they are close together
What’s deposition?
A gas turning into a solid
Why does the movement and arrangement of particles change during changes of state?
Because when energy is applied either hot or cold gets faster or slower. If it was melting a solid to a liquid the solid if getting hotter as more energy is applied therefore the particles start to move away from each other
Why does the energy of particles change during the changes of state?
Because as the particles warm up or cool down how fast or slow the particles vibrate changes?
What is happening when melting or boiling occurs?
The forces of attraction are being overcome
What are the 3 states of matter?
Solids, liquids, gases
What does the particle model explain?
Changes in a substance in terms of the arrangement, movement and energy stored in its particles
What are state changes?
Physical changes, they can be reversed and the chemical properties of the substance do not change, this is because the particles themselves don’t change, only their arrangement, movement and amount of stored energy
What are particles attracted to each other by?
Weak forces of attraction
