Problem

For a fixed amount of ideal gas, which of the following equations correctly relates the initial pressure and volume

(P_1, V_1)

to the final pressure and volume

(P_2, V_2)

when the temperature remains constant? a)

P_1V_2 = P_2V_1

\dfrac{P_1}{V_1} = \dfrac{P_2}{V_2}

P_1V_1 = P_2V_2

\dfrac{P_1V_1}{T_1} = \dfrac{P_2V_2}{T_2}
