Using... work = f xd, how much work is done if the force is 15.1 newtons and the distance is 35m?

They are all solids.

Ibelieve its because the stove is a cleaner burning fuel

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.
