JANAF thermodynamic tables are a set of reference tables containing thermodynamic data for chemical compounds. They provide information on the enthalpy, entropy, and Gibbs free energy of formation for various temperatures and pressures.
The JANAF (Joint Army-Navy-Air Force) Project was a collaboration between the US military and the National Bureau of Standards (now NIST). The tables were developed by a team of scientists and engineers in the 1950s and 1960s.
The JANAF thermodynamic tables were created to provide a comprehensive and reliable source of thermodynamic data for chemical compounds. They are used by scientists and engineers for various applications, such as designing and optimizing chemical processes.
Yes, the JANAF thermodynamic tables are still widely used by scientists and engineers, especially in the chemical and materials industries. However, they have been superseded by more modern databases and software in some applications.
The JANAF thermodynamic tables can be found in various online databases and software programs, such as NIST Chemistry WebBook and Thermo-Calc. They can also be accessed in print form in libraries and scientific institutions.
