    The total heat content of a system at constant pressure is equal to the sum of the internal energy and PV. This is called the enthalpy of a system which is represented by H.
    Note that enthalpy is also called as heat content.
    H = U + pv
    Enthalpy which depends on the three state functions: internal energy, pressure and volume.Hence it  is also a state function.
    Enthalpy of a substance cannot be measured, but change in enthalpy can be measured.
    Change in enthalpy =  Enthalpy of products - Enthalpy of reactants
    ∆H = HP-HR
    From the first law of thermodynamics
    ∆U =qp-P∆V
    qp =heat absorbed by the system
    -P∆V=work done by the system.
    For finite changes at constant pressure,       
    ∆H= ∆U+∆(PV)
    ∆H=∆U+P∆V         (∵ P is constant )         
    ∆H=qp            
    ∆H=-Ve for exothermic reactions
    ∆H=+Ve for endothermic reactions.
