The temperature of a gas is \( -78^\circ \text{C} \) and the average translational kinetic energy of its molecules is \( K \). The temperature at which the average translational kinetic energy of the molecules of the same gas becomes \( 2K \) is:
\( -78^\circ \text{C} \)
\( 127^\circ \text{C} \)
\( 117^\circ \text{C} \)
\( -39^\circ \text{C} \)
