Question

how does the strength of the forces that hold the basic particles of a substance together relate to the temperature at which the substance changes state?
a. weaker forces between particles means the substance boils at a higher temperature.
b. stronger forces between particles means the substance boils at a higher temperature.
c. stronger forces between particles means the substance boils at a lower temperature.
d. stronger forces between particles means the substance melts at a lower temperature.

Explanation:

The stronger the forces between particles, the more energy is required to separate them and change the state (e.g., from liquid to gas - boiling). Higher energy corresponds to a higher temperature.

Answer:

B. Stronger forces between particles means the substance boils at a higher temperature.
