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, where C is a constant. Then

A
If $${P_1} > {P_2}$$ then $${V_1} > {V_2}$$
B
If $${P_1} > {P_2}$$ then $${T_1} < {T_2}$$
C
If $${V_2} > {V_1}$$ then $${T_2} > {T_1}$$
D
If $${V_2} > {V_1}$$ then $${T_2} < {T_1}$$
