Do the Navier-Stokes equations include conservation of mass and energy?

Hi,

Stupid question: the Navier-Stokes equations, do they only consist of the equations for a statement of the conservation of momentum or do they also include the equations for conservation of mass (continuity equation), conservation of energy and an equation of state?

Thanks.

Only conservation of momentum.
