1.1 Solids, Liquids & Gases Flashcards
Define volume in a solid
Fixed
Define density in a solid
High Density
Define the vibration of atoms in a solid
They vibrate in a fixed position
Define volume in a liquid
Fixed, but take the shape of its container
Define density in a liquid
Generally denser than solids, but much denser than gases
Define movement of particles in a liquid
Move and slide over each other allowing liquids to flow freely
Define volume of gases
Not fixed and take the shape of its container
Define the density of gases
Very low density
Which state of matter can be compressed?
Gases
How is pressure created in a can of gas?
Particles of gas collide with each other
What is the arrangement of particles in a gas?
Randomly arranged
Change of state from Solid to Liquid
Melting
Change of state from Liquid to Gas
Evaporation
Change of state from Gas to Liquid
Condensation
Change of state from Liquid to Solid
Freezing
Change of state from Solid to Gas
Sublimation
Change of state from Gas to Solid
Deposition
Difference between melting and evaporation?
Melting occurs at a specific temperature, evaporation happens at any and at surface level
During a state change there is ____ temperature change
No temperature change
What do the horizontal lines on a heating/cooling curve show
Change in state but no change in temperature (latent heat)
As temperature increases what happens to volume of gas?
Increases
As volume increases what happens to density?
Decreases
What happens to gas particles when temperature increases?
Move faster
Define Diffusion
It is where particles move from an area of high concentration to an area of low concentration
