a method of separation purify water
milling it to take out the husk
1) separating salt and water 2) separating sugar and water exaples
evaporation is a kind of separation method it is used for separating a dissolved solid (solute) from a liquid
Distillation
Winnowing
It is used as a method of separation, it makes you check a substance's purity and different contents.
Filtering
The mixture of and and water is a heterogeneous mixture. There is two steps to separate: Sedimentation: The sand will settle at the bottom of the beaker Decantation: Pour the water slowly out of the container leaving the sand behind. This water is called "supernatant" liquid.
Either time OR a centrifuge.
Distillation can be used as a separation method.
when do we use method of separation? Let us describe it with an example. Let there be an time dependent schodinger eqn containing wave fn (which depends upon position and time),the k.E.term and the potential energy term.The wave fn can be written as a separation of variables i.e S(r,t) =A(r)B(t) when the potential is independent of time.
