Based on the reversibilities and irreversibilities described above I introduce 'S' as entropy. I then show that it comes from friction and heat transfer

Here I go through the two examples of a throttle and a heat exchanger. I look at the energy equation, and solve that. Then I look at the rate of entropy production. It is positive in both cases…

Here I describe what is hapenning in the two videos of the kid falling off the bike and the kid falling off the bike in reverse. I describe the natural order of things beign that order decreases and…

Here I show a series of irreversible processes. I discuss how in each case high quality energy is converted into lower quality energy and that this is inevitable. I introduce the concept of entropy.

Here I show some reversible processes and show that they cannot be really created. This shows the cause of entropy. FRICTION!

Here I introduce reversibilities and irreversibilities. I show that there is a natural way of things happening.
