... Hess’s law states that if a reaction is carried out in a series of steps, ∆H for the reaction will be equal to the sum of the enthalpy changes for the individual steps. Hess pointed out that the heat absorbed (or evolved) in a given chemical reaction is the same whether the process takes one step or ...

... If friction is involved, energy is still conserved, but mechanical energy is not necessarily conserved. Some of the mechanical energy can be converted to thermal energy through the work done against friction. Energy lost to friction is non-conservative. It is path dependent. Conservative quantities ...
