Which substance has the highest particle mobility?

A. Nitrogen gas at -200 °C because gas particles are the most mobile and mobility increases with decreasing temperature.

B. Water at 25 °C because liquid particles are the most mobile and mobility increases with decreasing temperature.

C. Ethyl alcohol at 30 °C because liquid particles are the most mobile and mobility increases with increasing temperature.

D. Steam at 105 °C because gas particles are the most mobile and mobility increases with increasing temperature.

Final answer:

Particle mobility is influenced by the strength of intermolecular forces, with substances possessing weak intermolecular forces having higher particle mobility. Gas particles typically demonstrate the highest mobility due to weak intermolecular interactions.


Explanation:

Particle mobility is influenced by the strength of intermolecular forces. In general, substances with weak intermolecular forces have higher particle mobility as the particles are more easily able to overcome these forces. Gas particles often exhibit the highest mobility compared to solid or liquid particles due to their weak intermolecular interactions.
