Study Notes
The equation of state for ideal gases is expressed as pV = nRT, describing the relationship between pressure, volume, and temperature. The Boltzmann constant links microscopic particle characteristics to macroscopic properties like temperature.
- Ideal Gas Equation — a formula that relates pressure, volume, and temperature of an ideal gas. Example: pV = nRT, where p is pressure, V is volume, n is the number of moles, R is the gas constant, and T is temperature.
- Boltzmann Constant — a constant used in the ideal gas equation, linking microscopic and macroscopic properties. Example: k = R/NA, where R is the molar gas constant and NA is Avogadro’s constant.
