How does the standard atmospheric pressure exhibited at sea level compare to the atmospheric pressure exhibited at the top of a tall mountain?

As the altitude increases, the atmospheric pressure decrease. On other words, the higher you go in a mountain, the lower the pressure gets.

The atmospheric pressure at the top of a tall mountain is much less pressure than that at sea level. This is because as you go up higher, there is less air pushing down on you. Hope this helped!

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.
