Abstract

We examine the thermodynamic properties of a viscous fluid known as viscous modified Chaplygin gas within the context of the homogeneous isotropic universe model. Physical parameter behavior in viscous fluid is discussed in order to analyze the nature of the universe. Our analysis shows how changes in the bulk viscosity parameter affect the universe’s thermodynamic characteristics. The specific heat formalism is used to analyze the validity of the third law of thermodynamics. Thermodynamic entities are also used to discuss the thermal equation of state. Thermodynamic stability is examined using isothermal, adiabatic, and specific heat conditions from classical thermodynamics. When appropriate parameters are selected, it is discovered that the fluid configuration under investigation expands adiabatically and is thermodynamically stable.
