a.)the solution's vapor pressure will be higher.
b.)the solution's vapor pressure will be lower.
c.)the solution's vapor pressure will be the same.
d.)the solution's vapor pressure will be twice as great.
e.)there is not enough information given to answer the question.

Asubstance is held in an open container. its particles move past one another at random speeds but do not leave the container. heat is removed from the system, and the particles slow down. when enough heat is removed, the particles no longer have enough speed to overcome the weak attractive forces between them. when this happens, the substance enters its solid state. the process described above is known as .
