Responder
La opción correcta es E: Las moléculas de diferentes gases con la misma masa y temperatura tienen la misma energía cinética media.
Solución
-
Según la teoría cinética de los gases, la energía cinética media de las moléculas depende únicamente de la temperatura.
-
La energía cinética media por molécula se expresa comodonde
es la constante de Boltzmann y es la temperatura. -
Esto implica que para gases diferentes, si tienen la misma masa y la misma temperatura, cada molécula tendrá la misma energía cinética media, independientemente de sus propiedades individuales.
-
Por lo tanto, la afirmación correcta es:
E. Moléculas de diferentes gases con la misma masa y temperatura siempre tienen la misma energía cinética media.

The statement that is true according to the kinetic theory is that molecules of different gases with the same mass and temperature always have the same average kinetic energy. This is because, according to the kinetic theory, temperature is a measure of the average kinetic energy of the molecules in a substance. So, if gases are at the same temperature, they’re moving with the same average energy, regardless of their type or mass.
Did you know that the kinetic theory of gases also underlies the principles of gas mixtures and ideal gases? In real-world applications, this theory helps engineers design everything from engines to refrigerators. When considering gases in different scenarios, understanding how temperature impacts kinetic energy is crucial for predicting how gases will behave. It’s fascinating how this theory connects so many aspects of science and technology!
