Abstract
It is shown how information contained in the pairwise correlations in general partial between atoms of a gas can be used to completely convert heat taken from a thermostat into mechanical work in a process of relaxation of the system to its thermal equilibrium state Both classical correlations and quantum correlations entanglement are considered The amount of heat converted into work is proportional to the entropy defect of the initial state of the system For fully correlated particles in the case of entanglement the amount of work obtained per particle is twice as large as in the case of classical correlations However in the case of entanglement the amount of work does not depend on the degree of correlation in contrast to the case of classical correlations The results explicitly demonstrate the equivalence relation between information and work for the case of twoparticle correlations
