Predict which change would cause the heat of vaporization (segment 4) segment to be longer.
A) Add heat at a faster rate.
B) The amount of the substance decreases.
C) The boiling point temperature increases.
D) The intermolecular forces of the substance get stronger.
Eliminate
The intermolecular forces of the substance get stronger.
If the intermolecular forces increase in strength, the particles require more heat energy to separate them. As a result the heating time would be lengthened.
