It may help your daughter to get full marks if she spells 'separate' correctly, ellywellywoo :-)
(Unless her teacher is under 40, in which case it will probably make no difference.)
Follow Muppit's advice, but spell 'evaporate' and 'apparatus' correctly. :-)
Teddio is also correct, but is wrong about the boiling point of the salt in water solution. The boiling point of the solution will be slightly higher than 100�C (just as its freezing point will be slightly lower than 0�C). The difference will be very slight, too small to notice, probably, but worth knowing, if you take science seriously.
