An ideal gas follows a process described by the equation P V^2=C from the initial (P_1, V_1, T_1) to final (P_2, V_2, T_2) thermodynamic states,…
An ideal gas follows a process described by the equation $\displaystyle P V^2=C$ from the initial $\displaystyle \left(P_1, V_1, T_1\right)$ to final $\displaystyle \left(P_2, V_2, T_2\right)$ thermodynamic states, where $\displaystyle C$ is a constant. Then
Official answer
(4)
If $\displaystyle V_2>V_1$ then $\displaystyle T_2<T_1$
