Question

1. a. how can we separate salt from water? include a diagram.

p29
heat it up so the water evaporates while the salt particles stay
b.
in the above diagram does the water evaporate?
in the above diagram does the salt evaporate?
what change of state does the water go through before it enters the beaker?

Explanation:

The problem asks how to separate salt from water, which is a mixture of a soluble solid and a liquid. The standard method for this separation is evaporation: heating the saltwater solution causes the water to evaporate (change from liquid to gas), leaving the solid salt behind. The diagram likely illustrates this process with heat applied to the solution, water vapor escaping, and salt remaining.

For part B:

1. Water evaporates (liquid → gas).
2. Salt does not evaporate (remains solid).
3. Water changes from liquid to gas before entering the beaker (it evaporates as vapor first).

Answer:

A. Separate salt from water by evaporation: Heat the saltwater solution—water evaporates, leaving solid salt.
B.

1. Yes
2. No
3. Liquid to gas
