Calculate the heat change involved when 2.00 L of water is heated from 20.0GC to 99.7GC in an electric kettle

The answer for this is a

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.
