Answer

Explanation:

Step1: Aplicar la ley de Charles - Gay - Lussac

Para un gas a presión constante, $\frac{V}{T}=k$ (constante), donde $V$ es el volumen y $T$ es la temperatura en Kelvin.

Step2: Analizar el efecto de enfriar

Si se enfría el gas (temperatura $T$ disminuye), y la presión permanece constante (atmospérica), para mantener la igualdad $\frac{V}{T}=k$, el volumen $V$ también debe disminuir.

Step3: Descartar otras opciones

El número de moles no cambiará porque no hay entrada o salida de gas (el gas está atrapado). Y la temperatura no aumenta sino que disminuye al enfriar.

Answer:

D. The volume of the container will decrease.
