    The condensation heat transfer coefficient on HPI-SLIPS was enhanced by 113.8–120.3% and 27.4–44.8% as compared to those of HPO and HPO-SLIPS within the subcooling degree from 33.6 K to 10 K when the nitrogen volumetric content was 9.2% (see Fig. 11(b)). Moreover, this enhancement improved when the nitrogen content increased (see Fig. 11(c)

    Owing to the fact that heat is a form of energy, it has the SI unit ofjoule (J). Thecalorie (cal) is a common unit of energy, defined as the energy needed to change the temperature of 1.00 g of water by1.00ºC —specifically, between14.5ºC and15.5ºC, since there is a slight temperature dependence.
