Question

which two correctly relate the attraction between the particles of a liquid and the temperature at which the liquid changes state? a. strong attractions mean the liquid boils at a lower temperature. b. strong attractions mean the liquid melts at a lower temperature. c. strong attractions mean the liquid boils at a higher temperature. d. strong attractions mean the liquid melts at a higher temperature.

Explanation:

When particles in a liquid have strong attractions, more energy (higher temperature) is needed to overcome these attractions. Boiling is the process of changing from liquid to gas (overcoming attractions to separate particles more), and melting is changing from solid to liquid. Stronger attractions mean higher boiling and melting points as more energy (higher temperature) is required to change the state.

Answer:

C. Strong attractions mean the liquid boils at a higher temperature.
D. Strong attractions mean the liquid melts at a higher temperature.
