An example of a metaphor (to an alternative conception) used in popular science writing:
"For an engine to keep going, some of the work created during expansion must be sacrificed, pressing the piston back to its starting position…heat must be sucked out of the cylinder into a sink in this compression stage."
"The ideal refrigerator takes the fifty calories' worth of work from the ideal engine, sucks fifty up from the sink, and pumps one hundred calories into the furnace."
"Behind the refrigerator's inner wall is a network of pipes called an evaporator. The coolant evaporates inside it, sucking heat out of the device's interior at a constant temperature of 4˚C."
