New-hire full-time airline baggage handlers at large US airlines earn gross average salaries of around $21,000 annually, or $10 per hour. Many airline baggage handlers, though, start out as part-time hires, meaning they'll make about $10,400 annually to start.
Free Energy is a thermodynamic quantity given by the subtraction between the internal energy of a system and the product of its absolute temperature and entropy. In Chemistry terms, it is also known as the difference between the enthalpy and the multiplication of the absolute temperature and entropy of a system, Gibbs Free Energy.
Heat is defined in physics as the transfer of thermal energy across a well-defined boundary around a thermodynamic system. The thermodynamic free energy is the amount of work that a thermodynamic system can perform.
