Concept introduction:Thermodynamics is a study of energy transfers that can be done by either heat or work. The energy transferred through work involves force. When work is positive, the system gains energy,whereas, when work is negative, the system loses energy. Heat is not a state function, and therefore, change in enthalpy of reaction
