At room temperature nitrogen is a gas and Mercurys a liquid how did the particles of nitrogen gas compared to the particles of liquid mercury

Yapo 13 fool coming at you for it

The answer is 4 i don't know if its right let me see.

Answerδh > 0explanationc₆h₆  (s)  → c₆h₆ (l)if you are changing it from a solid to a liquid, you are pretty much melting the solid. this requires heat energy. therefore, the reaction is endothermic (takes in energy); the system enthalpy increases as the reaction proceeds: δh > 0.
