The diagram above represents the phases of the moon. Position 1 represents the new moon. Positions 2 through 8 represent the phases of the moon that follow.
How many days does it take to get from 1 to 5?

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 process is c.convection
