Adding salt to a solid decreases the freezing point of that solid.
When seawater freezes, salt is expelled from the solid in a concentrated salt solution called brine.
Salt is expelled from seawater as it freezes at the freezing point.
What happens to salt in seawater as it freezes at the freezing point?
A) vaporization
B) boiling
C) expelled
D) salinity
E) evaporation
F) less water
G) water vapor
H) Temperature
