Calculate the gravitational field strength at Pluto surface show the work

What do you mean by that? like the contents? the thc level?

Answeramino acids;

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.

The answer is solid copper
