La opción correcta es B: El oxígeno tendrá más energía cinética que el nitrógeno.
Solución
-
La energía cinética promedio de las moléculas de un gas se relaciona directamente con la temperatura absoluta, dada por la fórmuladonde
es la constante de Boltzmann y la temperatura. -
Si solo se aumenta la temperatura del oxígeno, la energía cinética de las moléculas de oxígeno aumenta, mientras que la del nitrógeno permanece constante (al estar en STP sin cambio de temperatura).
-
Por lo tanto, el oxígeno tendrá una mayor energía cinética que el nitrógeno.
La respuesta correcta es la opción B.

When you increase the temperature of just the oxygen gas, the average kinetic energy of the oxygen molecules increases because kinetic energy is directly proportional to temperature. Since nitrogen’s temperature remains constant, its kinetic energy will stay the same. Thus, the correct conclusion is that the kinetic energy of oxygen will be greater than that of nitrogen immediately after the temperature increase.
When it comes to real-world applications, understanding the behavior of gases under temperature changes is crucial in fields like meteorology and aviation. For instance, in aviation, different gas compositions in the atmosphere can affect lift and drag on aircraft during flight. That’s why pilots need to keep a close eye on temperature and pressure conditions!
