Particles Flashcards
To revise particles
What are the three main states of matter?
Solids, liquids and gasses
What are the four properties of each state that help define them?
Compression, shape, movement of particles and forces between them.
Describe the properties of a solid using the four descriptors (compression, shape, movement, forces between particles)
Compression-no
Shape-fixed shape
Movement-none
Forces between particles-strong
Describe the properties of a liquid using the four descriptors (compression, shape, movement, forces between particles)
Compression-small amount
Shape-takes shape of container
Movement-yes
Forces between particles-weaker than solids
Describe the properties of a gas using the four descriptors
Compression-yes
Shape-no fixed shape
Movement-yes
Forces between particles-Very very very weak
What are the three changes in state?
Gas to solid
Solid to liquid
Liquid to gas
Vice-versa
What is the process called of the solid going to a liquid and vice-versa
Melting and freezing
What is the process called of a liquid going to a gas and vice-versa
Evapouration and condensation
What is the process called of a solid going to a gas and vice-versa
Sublimation and deposition
Define pressure
The amount of force that is applied to a surface per unit area. The larger the surface area the lower the pressure
