Introduction the purpose of the lab was to determine how the solubility of borax (na2b4(oh)4) and other thermodynamic quantities such as enthalpy, entropy, and gibbs free energy depend on temperature.
These results, along with heat capacities for borax and tincalconite determined by dsc and molar volumes determined by xrpd, were used to assess the thermodynamic properties of borax dehydration as a function of temperature and pressure. Taken from the nbs tables of chemical thermodynamic properties (1982) and crc handbook of chemistry and physics, 1st student edition (1988). Understanding thermodynamics through the concepts of absolute zero and the distribution of molecular speeds thermodynamics is the study of work, heat, and the energy of a system (nasa, 2010) to help explain in more detail the properties of thermodynamics are the laws of thermodynamics.
