Also known as heat cycle. thsr-mo-dT nam-ik sT-ksl thermodynamic efficiency IND ENG An index for rating the effort required by a worker performing a task in terms of the ratio of work performed to the energy consumed. thsr-mo dT nam-ik i fish-sn-se thermodynamic equation of state thermo An equation that relates the reversible change in energy of a thermodynamic system to the pressure volume and temperature. thsr-mo dT nam-ik i kwa-zhsn sv stat thermodynamic equilibrium thermo Property of a system which is in mechanical chemical and thermal equilibrium. thsr-mo dT nam-ik e-kws lib-re-sm thermodynamic function of state thermo Any of the quantities defining the thermodynamic state of a substance in thermodynamic equilibrium for a perfect gas the pressure temperature and density are the fundamental thermodynamic variables any two of which are by the equation of state sufficient to specify the state. Also known as state parameter state variable thermodynamic variable. thsr-mo dT nam-ik fsgk-shsn sv stat thermodynamic potential thermo One of several extensive quantities which are determined by the instantaneous state of a thermodynamic system independent of its previous history and which are at a minimum when the system is in thermodynamic equilibrium under specified conditions. .
