This video uses a Carnot cycle to determine the thermodynamic efficiency of a heat engine.

This video demonstrates that entropy is a state function by calculating the change in entropy in a Carnot cycle

Textbook sections covered: 1.4.1 to 1.4.4

This video describes the Joule-Thomson effect in the context of the variation of the enthalpy with pressure. It showcases an isenthalpic process that allows to determine the Joule-Thompson coefficient

This video describes how the enthalpy depends on temperature and pressure. The Joule-Thompson coefficient is introduced.

This video describes the variation of internal energy with temperature at constant pressure. The expansion coefficient and isothermal compressibility of substances is used to establish universal relationships between the heat capacities at constant pressure and volume. There is an error in the definition of isothermal compressibility at 8:50. Kappa_T=-1/V(dV/dP)_T rather than -1/V(dV/dT)_P. Tha...

This video describes the variation of the internal energy with volume and temperature and introduces the concept of internal pressure.

This video derives a relationship between the initial and final pressures and volumes of an adiabatic expansion of an ideal gas

This video derives a relationship between the initial and final temperatures and volumes in an adiabatic ideal gas expansion

This video provides a foundation to understand adiabatic gas expansions. It provides an understanding of how to calculate work and the change in internal energy.

This video shows how to obtain the heat capacity at constant volume for an ideal gas from the equipartition of energy principle

This video describes how the heat capacity at constant volume of a substance provides the variation of the internal energy of the substance with temperature at constant volume.
