61.   The body generates heat through metabolism, using food as energy.

62.   The chemical reaction that produces the oxygen also generates heat, and in normal use, the generators are well insulated to prevent surrounding material from catching fire.

63.   The contraption generated enough heat to melt the cheese, at first slowly, then faster and faster.

64.   The compost is finished when the pile no longer generates heat.

65.   The heat is generated where it is used.

66.   The most heat was generated in the Street Stock race.

67.   The plays, both directed by their authors, are far from perfect, but on the stage they definitely generate heat.

68.   The pools have mechanical cooling and filtration systems that circulate water past the spent fuel rods, which continue to generate heat years after being removed from the reactor.

69.   These lights generate heat so they must have at least three inches clearance space on all sides for cooling.

70.   They can also generate enough heat to melt copper electrical wires and start fires.
