Thermodynamics is the science of the flow of heat. So, thermo is heat, and dynamic is the motion of heat. Thermodynamics was developed largely beginning in the 1800’s, at the time of the Industrial Revolution. So, taming of steel. The beginning of generating power by burning fossil fuels. The beginning with the problems with CO2 and global warming. In fact, it’s interesting to note that the first calculation on the impact of the CO2 on climate was done in the late 1800’s by Arrhenius. Beginning of a generation of power moving heat from fossil fuels to generating energy, locomotives, etcetera. So, he calculated what would happen to this burning of fossil fuels, and he decided in his calculation, he basically got the calculation right, by the way, but he came out that in 2,000 years from the time that he did the calculations, human would be in trouble.
The lecture is about thermodynamic theory and kinetic theory, which are major development of physics. Thermodynamics is about heat and temperature transmission and their relation to energy and work.
The laws of thermodynamic are constant and statistical, describing how quantities behave under various circumstances.
Thermodynamics are obeyed under most situations, although there are exceptions where atoms move randomly with kinetic energy.
