What does a particular point on a line of a phase diagram represent? A. The pressure created by the kinetic energy of molecules at a
particular temperature
B. The maximum temperature a substance can exist at without
bonds breaking
C. The melting point or boiling point of a substance at a specific
pressure
D. The conditions in which temperature and pressure have equal
effects on a substance

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 .
