Experimental Analysis of Deviations of Real Gases from Ideal Gases at Constant Temperature
type: item
description: This research aims to examine the deviations in experimental results of real gases from the ideal gas model at a constant temperature. The research method involves using specially designed and developed experimental apparatus to measure the pressure and volume of gases at various pressure variations up to 600 KPa. The pressure and volume data of gases are analyzed by comparing the Van der Waals Gas model with the ideal gas model. The analysis results indicate that the Van der Waals Gas model is significantly more accurate in modeling the behavior of real gases compared to the ideal gas model. The Van der Waals Gas model has a lower Root Mean Square Error (RMSE) value (1509.8 Pa) and a coefficient of determination (R square) value approaching 1 (0.99), while the ideal gas model exhibits a high RMSE (352121.0 Pa) and a low R square (0.082). Deviations from ideal gas behavior occur at high pressures (above 150,000 Pa) and low pressures (below 90,000 Pa), while within the pressure range between these two points, the ideal gas model still provides reasonably good results. The Van der Waals gas model is significantly more accurate than the ideal gas model in modeling the behavior of real gases at a constant temperature.
