<p>Al vaporizarse una sustancia, a la temperatura de ebullición (#te ºC) y a la presión constante de #pa atm, se absorben #env Kcal. El sistema realiza trabajo sobre la atmósfera que le rodea, a causa de la variación de volumen que tiene lugar cuando la sustancia pasa de líquido a vapor. Calcula el trabajo, en KJ, realizado por 1 mol de sustancia (masa molecular =38), sabiendo que su densidad en estado líquido a esa temperatura es de #dens g/cm<sup>3</sup> </p> <p>(1 J = 0.24 cal; 1 atm= 101325 Pa)</p>
