- - - - step up transformers
        
        step down transformers
        
        households
- - - - when gass molecules repeatedly hit the side of a container the total effect of this is called pressure
      - as the particles become hotter the particles will collide with the sides of a container faster therefore the pressure is greater causing the container to expand.
      - when decreasing the volume their will be less particles hitting the sides of the container reducing the pressure.
- - - - the specific heat capacity of a material
    - - the types of material used
    - - energy=power*time
  - - - the variable effecting the wire eg length,width
    - - the effect of certain variables upon ressisatance
- - - - work done=force*mass
- - - - the light provides energy causes electron to move up shells
        
        once enough energy is provided to the electron it can escape from the atom meaning it Is ionised
  - - - activity - this is the amount of radioactive decay per second
        
        alpha - when an atom decays it releases 2 protons and 2 neutrons as well as an alpha particle. = A helium nucleus emitted by some radioactive substances
        
        beta - is just an electron that's formed from a neutron and is high charged
