Abstract: The low-temperature thermodynamic variables of entropy, internal energy and specific heat capacity of a liquid 3He-4He binary system have been studied. The system showed a remarkable discontinuity in internal energy at about 2.14 K. In the binary mixtures, the bosonic components have been studied by means of modified Gross-Pitaevskii (GP) approximations and the fermionic components by Thomas-Fermi (TF) approximations. Equations for particle and energy distributions have been developed. The effects of the nature of scattering lengths have been studied. Implications on selected Bose-Fermi mixtures such as 7Li-6Li and 41K-40K are discussed.
