The kinetic molecular theory states that all particle of an ideal gas are A. colliding without transferring energy

B. in random, constant, straight-line motion

C. arranged in a regular geometric pattern

D. separated by small distance relatives to their size

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.

is the answers your welcome! : )

Aand x are the answers to your question.hope it !
