At \( T(K) \), in a closed vessel, a gas obeying the kinetic theory of gases has two molecules. The kinetic energy of these molecules is \( x_1 \) J and \( x_2 \) J respectively. After a few collisions, their kinetic energy is \( y_1 \) J and \( y_2 \) J respectively. Identify the correct relationship/s:

(1) \( x_1 = y_1 \)

(2) \( \frac{x_1 + x_2}{2} = \frac{y_1 + y_2}{2} \)

(3) \( x_2 = y_2 \)

(4) \( (x_1 - x_2)^2 = (y_1 - y_2)^2 \)
