Tasks of the thermodynamics:

  • Search for common physical regularities.
  • Search for the thermal equilibrium.
  • Search for suitable physical dimension (variables of state), which describe the macroscopic characteristics of the subject.
  • Search for generally accepted relations between the variables (equations of state, main clauses).
  • Search surrounding field is the sum of daily experiences.
