For water near 0°C, $L_{f} = 334 kJ / kg$ and $L_{v} = 2500 kJ / kg$ . Estimate the latent heat of sublimation of ice at 0°C in kJ/kg, treating sublimation as melting followed by vaporization at the same temperature.

Answer:

2834.00

Solution:

$L_{sub} \approx L_{f} + L_{v} = 334 + 2500 = 2834 kJ / kg$ . It is larger than either one, which is why $L_{f} < L_{v} < L_{sub}$ .
