We consider the compressible (barotropic) Navier-Stokes system on time-dependent domains,
supplemented with slip boundary conditions. Our approach is based on penalization of the
boundary behaviour, viscosity, and the pressure in the weak formulation. Global-in-time weak
solutions are obtained. Secondly, we suppose that the characteristic speed of the fluid is domi-
nated by the speed of sound and perform the low Mach number limit in the framework of weak
solutions. The standard incompressible Navier-Stokes system is identified as the target problem.
