In this study, we examine the thermal properties of the medium formed in ultra-relativistic heavy-ion collisions at chemical freeze-out using a thermal model. We utilize experimental data on various hadron species from 0 to 5 most central Au+Au collisions at sNN=7.7 GeV from the STAR BES program to analyze the thermal properties, namely, chemical freeze-out temperature, baryon chemical potential, and strangeness chemical potential. We employ a �2 minimization technique to obtain these thermal properties. Furthermore, we also obtain thermal properties with strangeness conservation condition and at zero potentials μB� T=μS� T=0. We compare particle ratios from the thermal model with the experimental data. The thermal model describes particle ratios within ±2.5 standard deviations and �2� NDF between 1-2. We also discuss the collision energy dependence of thermodynamic properties of the medium at freeze-out and compare results with the published STAR results and other thermal model calculations. © 2024 World Scientific Publishing Company.
