"In the first tutorial, we looked at how to solve for the entropy of mixing for a regular solution, and then we looked at how a highly ordered system with and uneven distribution of two species tends ...

In combustion reactions, some substances will release more energy than others. Enthalpies of combustion can be used to compare which fuels or substances release the most energy when they are burned.

Energy is required to break a covalent bond between two atoms to overcome the attractive force. Bond breaking is an endothermic process. The opposite is true if we want to make new bonds. Energy is ...

Enthalpy, H is the name given to a grouping of thermodynamic parameters: H = U + PV. The enthalpy per unit mass is the specific enthalpy, h = u + pv. It is a function of the state of the system.

Exact numerical solutions of the flame equations are presented for a class of one-dimensional pre-mixed steady flames propagating in the presence of an enthalpy gradient. It is shown that a positive ...
