Pure substances are (1)
in appearance. During boiling, the temperature of a
changes at the start then it becomes (3)
During melting, a substance melts
within a short time
To determine a (5)
sample if it is a pure substance, you should test it using its
boiling point, while if it is a (5)
sample, its melting point is the best way to test.
In Enrichment A, the liquid Ais (7)
since it has a fixed boiling point while the water with salt
is a mixture because it has a varying melting point
