) je energija koja se prenosi preko granica sustava bez prijenosa mase, a koja je izravno povezana s djelovanjem makroskopske sile na određenom putu. Volumetrijski rad (Rad širenja/sabijanja)
A lab section described a simple experiment: heat a measured mass of water, record temperatures, calculate specific heat and losses to the surroundings. The instructions were almost affectionate in their precision: calibrate the thermometer, stir gently, wait for equilibrium. There was a subtle respect for the patient work of getting numbers right, for the craft of measuring rather than merely quoting formulas.

The chemical energy release used in thermal power plants. There was a subtle respect for the patient
Outside the library the evening had grown cold. I hardly noticed at first; the equations in my head kept the world measured and understandable. I thought about entropy—not just the technical quantity that governs energy dispersal, but the everyday drift toward disorder: an old radiator clogging, a maintenance schedule missed, a system losing efficiency. The PDF’s insistence on measurement and checklists felt like a method for fighting entropy—deliberate acts that keep things running, predictably.
Energija se ne može stvoriti niti uništiti, samo transformirati.
