Describe the changes of state that occur during the distillation process.

1.E

●The liquid mixture is h until one of the liquids begins to e .

●The particles… (talk about energy here)

●During e , a l turns into a .

●The particles s o and are no longer t .

2. C

●The particles in the g enter the c

●The particles… (talk about energy here)

●The cold w surrounding the outside of the tube causes the vapour to c , turning back to a l from a g .

●The particles move c together and are t again.
