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
Dehydration. Dehydration also increases heart rate during exercise. Sweating draws water from the blood and, over time, leaves less blood flowing through your heart and to your muscles, reducing oxygen supply to the muscles.eart rate is an indicator of metabolic needs of the muscles during exercise.
