So the change in enthalpy to go from solid to a gas directly (sublimation) at some temperature is equal to the sum of the enthalpies associated with going from a solid to a liquid (fusion) and going from a liquid to a gas (vaporization) at other temperatures.hy is the enthalpy of sublimation is equal to the sum of enthalpy of fusion and enthalpy of vaporization?
17. An important way to restore intra-vascular volume is the foremost goal of hydration during exercise which can be done with 0.9% saline and so the second point is justified. Avoiding GI ups... view the full answer
