This change of thermal energy in the thermodynamic system is known as change of enthalpy or delta h written as ∆H in chemistry and calculated using the formula ∆H = cm∆T. Note that the
Brought to you by Sciencing ∆H = ∆U + P∆V However, for a constant pressure, the change in enthalpy is simply the heat (q) transferred: ∆H = q If (q) is positive, the reaction is
