An ideal gas follows a process described by the equation \(PV^2=C\) from the initial \((P_1, V_1, T_1)\) to final \((P_2, V_2, T_2)\) thermodynamics states, where \(C\) is a constant. Then:
1. \(\text{If}~P_1>P_2~\text{then}~T_1<T_2\)
2. \(\text{If}~V_2>V_1~\text{then}~T_2>T_1\)
3. \(\text{If}~V_2>V_1~\text{then}~T_2<T_1\)
4. \(\text{If}~P_1>P_2~\text{then}~V_1>V_2\)

\(1\) g of water of volume \(1\) cm3 at \(100^\circ \text{C}\) is converted into steam at the same temperature under normal atmospheric pressure \(\approx 1\times10^{5} \) Pa. The volume of steam formed equals \(1671\) cm3. If the specific latent heat of vaporization of water is \(2256\) J/g, the change in internal energy is:
1. \(2423\) J
2. \(2089\) J
3. \(167\) J
