When we learned material balances, we were able to track the movement of chemical species throughout a system or process.

Another important aspect of process analysis is the determination of the energy requirements and temperatures around systems. For instance, how can we maintain a consistent temperature in a reactor if the reaction inside is exothermic? How much energy do we need to add to a process stream to move it to some new temperature?

There are three forms of energy that we will consider (expressed per mass of material):

Just as a flowing stream has kinetic and potential energy, individual molecules also have kinetic energy (from their individual motion) and potential energy (from the attraction and repulsion between molecules).

The sum of these molecular energies is expressed as the internal energy of the material, which is a strong function of temperature.

Now, the total energy per mass of material is

Our generalized conservation of energy equation is therefore
