States Of Matter + Particles (1) Flashcards
What are the 3 states of matter
Solid
Liquid
Gas
The strength of the forces of attraction between particles depend on what 3 things
The material
Temperature
Pressure
In solids, there are __________ forces of attraction between particles, which holds them close together in __________ positions to form a very regular ____________ arrangement
Strong
Fixed
Lattice
In ___________ particles don’t move from their positions, so they all keep a definite shape and ___________ and don’t flow.
Solids
Volume
In solids, particles __________ about their positions - the hotter the solid becomes, the _________ they vibrate (causing solids to __________ slightly while heating)
Vibrate
More
Expand
In liquids there is a _________ force of attraction between the particles. They’re _____________ arranged and free to move past each other, but they tend stick closely together
Weak
Randomly
Liquids have a definite ___________ but don’t keep a definite __________ and will flow to fill the bottom of a container
Volume
Shape
In ____________, particles are constantly moving with random motion. The hotter the liquid gets the ____________ they move. This causes them to ___________ slightly when heated.
Liquids
Faster
Expand
In gases, the forces of attraction between the particles are very ________- they’re free to move and are far apart. The particles in gases travel in straight __________
Weak
Lines
Gases don’t keep a definite _________ or __________ and will always fill any container
Shape
Volume
Particles in gases move constantly with ____________ motion. The hotter the gas gets, the ____________ they move. Gases either expand when heated, or their ___________ increases
Random
Faster
Pressure
Physical changes don’t change the particles - just their arrangements or their ____________
Energy
When a solid is heated its particles gain more __________. This makes the particles vibrate more which ___________ the forces that hold the solid together. This makes the solid ____________. At a certain temperature, the particles have enough energy to break free from their positions. This is called _____________ and the solid turns into a liquid
Energy
Weakens
Expand
Melting
When a liquid is heated, the particles get more __________. This makes the particles move ___________ which weakens the bonds holding the liquid together. At a certain temperature, the particles have enough energy to break their bonds. This is called __________________ and the liquid turns into a gas
Energy
Faster
Evaporating
What is a gas turning into a liquid called
Condensing
