In this paper we consider a variety of initial-boundary value problems for the p'th power Newtonian fluid in one space dimension. We extend previously known results for the ideal gas case to a more general p'th power gas law, subject to the pinned endpoints and Dirichlet or Neumann temperature boundary conditions. The exponential convergence of the temperature, velocity and density is established for generic initial data. The estimates for different boundary conditions are presented in a unified manner.
