Measurement of Air Density & Universal Gas Constant for Heat Physics Lab

This Measurement of Air Density & Universal Gas Constant for Heat Physics Lab is designed for studying the thermodynamic properties of gases and experimentally determining the density of air and the universal gas constant. The apparatus utilizes the vacuum method, combining a gravity bottle, vacuum pump, vacuum gauge, and precision mass measurement techniques to investigate the relationship between pressure, volume, temperature, and gas mass. Through practical experimentation, students can verify the ideal gas law, determine air density under ambient and standard conditions, and calculate the universal gas constant with high accuracy. The system provides an effective platform for thermodynamics and molecular physics laboratory studies.
