Most rare diseases are genetic, and thus are present throughout the person's entire life, even if symptoms do not immediately appear. Many rare diseases appear early in life, and about 30 percent of children with rare diseases will die before reaching their fifth birthday. With a single diagnosed patient only, ribose-5-phosphate isomerase deficiency is considered the rarest genetic disease.
When the temperature in the core reaches about 100 million degrees, the helium will begin to fuse into carbon by a reaction known as the triple-alpha process, because it converts three helium nuclei into one carbon atom.This generates a great deal of heat.n heavier stars, the oxygen can in turn fuse with the helium to make neon.) Helium fusion produces only 9% as much energy per kilogram as hydrogen fusion, so energy-wise, the Sun continues to be mainly a hydrogen reactor. 90% of its luminosity still comes from burning hydrogen.
Theory The heat of vaporization of a liquid is the energy that must be supplied in order to convert a unit mass of the liquid to the gas phase. A typical unit is Joules/gram (J/g). Liquid nitrogen at atmospheric pressure has a boiling point of 77.3 K and remains at its boiling point throughout the experiment.se Igor to produce graphs of mass versus time and determine the three rates of vaporization via a linear fit to the data using Igor. Remember, for each rate you are making a linear fit to a part of the data. 6. Calculate the latent heat L and compare it to the accepted value of 199.5 J/g for liquid nitrogen.
