Calorimetry: Phenomenological Laws and Heat Transfer

This lecture covers the phenomenological laws related to temperature, volume, pressure, and number of moles of a dilute gas, including Boyle-Mariotte, Charles, Gay-Lussac, and Avogadro's laws. It also discusses reversible heat transfer, calorimetric coefficients, specific heats, the third law of thermodynamics, and the Mayer relation. Practical experiments on Boyle-Mariotte's law and specific heat capacities are demonstrated. The lecture further explores the calorimetric coefficients dependent on temperature and volume or pressure, as well as the specific heats of solids and gases. It concludes with the principles of the third law of thermodynamics and the ideal gas equation of state.
