Gas Laws: Phenomenological Principles

This lecture covers the four phenomenological laws that relate the temperature, volume, pressure, and number of moles of a dilute gas: Boyle-Mariotte's law, Charles's law, Gay-Lussac's law, and Avogadro's law. It also discusses the synthesis of these laws into the ideal gas law, illustrated through experiments demonstrating the constancy of the product of pressure and volume. The lecture further explores experiments showcasing the constancy of volume-temperature ratios and pressure-temperature ratios in ideal gases.
