Página 96 - ... expands in a nonconducting cylinder, and during its expansion performs mechanical •work, its pressure falls — (1) On account of increase of volume; (2) because of liquefaction. The performance of work by the steam causes an equivalent loss of heat, and the amount of heat transformed into work, is sufficient, not only to lower the temperature of the steam to that corresponding to its reduced pressure, but also to cause liquefaction of a portion of it. When a small portion liquefies, it liberates...
