An ideal gas undergoes four different processes from the same initial state as shown in the figure below. Those processes are adiabatic, isothermal, isobaric, and isochoric. The curve which represents the adiabatic process among \(1,\) \(2,\) \(3\) and \(4\) is: 
          
1. \(4\) 2. \(1\)
3. \(2\) 4. \(3\)

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. \(\text{If}~P_1>P_2~\text{then}~V_1>V_2\)
