Imagine that we have three containers of ideal gas labeled A, B and C. Gas A is green, gas B is yellow, and gas C is red. All three containers

contain the same amount of gas and are at the same temperature. The container holding A is three times the volume of the container holding B, and the container holding C is half the volume of the container holding B so: 3 V_{A}=V_{B}=\frac{1}{2} V_{C}, T_{A}=T_{B}=T_{C}, \text { and } n_{A}=n_{B}=n_{C} 3 U_{A}=U_{B}=\frac{1}{2} U_{C} U_{A}=U_{B}=U_{C} \frac{1}{3} U_{A}=U_{B} U_{A}=6 U_{C} 3 U_{A}=U_{B}=6 U_{C}
