Abstract
We formulate thermodynamical relations based on the field degrees of freedom by introducing a work induced by the volume change in the function space, in addition to the usual work associated with the spatial volume change. The first and second laws of thermodynamics are defined for such a work inherent to the field theory by generalizing stochastic energetics (stochastic thermodynamics) to the classical real scalar field in contact with a heat bath. We further discuss the local equilibrium ansatz in the function space and show that it is possible to introduce a model of functional ideal hydrodynamics, which is consistent with the derived thermodynamical laws.
