physics
- solids
- strong forces of attraction
- fixed
position
- all touching
- no space between the particles
- cannot be compressed
- strong forces of attraction
- liquids
- 75% touching
- cannot be compressed
- weak forces of attraction
- can flow
- can change shape
- can pe poured
- 75% touching
- gases
- none touch
- rapid,random motion
- Flow
- Flow
- no force of attraction
- a lot of space between particles
- no pattern
- none touch
- heating curves
- the plot of temperature
- shows changes of state
- you can read the melting and boiling points
- temperature of the substance against the amount of energy it has
absorbed
- the plot of temperature
- Specific
latent heat
of fusion
- The amount
of energy
needed to
melt 1kg of a
solid into a
liquid
without
changing its
temperature
- The amount
of energy
needed to
melt 1kg of a
solid into a
liquid
without
changing its
temperature
- Specific
latent heat
of
vaporisation
- The amount
of energy
needed to
boil 1kg of a
liquid to a
gas without
changing its
temperature
- The amount
of energy
needed to
boil 1kg of a
liquid to a
gas without
changing its
temperature
- Sublimation
Melting. Boiling
Solid, liquid, gas
Freeze,condense
Depostion
- Mass = densityXvolume
- E=mxL
- Specific
heat
capacity
- Amount of
energy
needed to
change 1kg
of a
substance
by 1
degrees
- Amount of
energy
needed to
change 1kg
of a
substance
by 1
degrees
- P1V1=P2V2
- Energy cannot be created or destroyed ,it can only be transferred from one store to another
- pathway examples
- The sun has a store of nuclear energy which reaches the solar cells through a radiation pathway.
- The energy is stored in a battery when the machine is used some energy is wasted this happens through a heating pathway.
- The sun has a store of nuclear energy which reaches the solar cells through a radiation pathway.
- eqations
- ep = m x g x h
- ee = 1/2 x k x exe
- ek = 1/2 x m x vxv
- wd = f x d
- p = wd divided by t
- ep = m x g x h
