Answer
$T_f=170K$
Work Step by Step
The equation to be used here is:
$\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}$
This equation can be rearranged to:
$T_2=\frac{P_2V_2}{P_1V_1}T_1$
Putting the values into this equation and solving:
$T_2=\frac{(4.6)(4\times10^{-3})}{(32)(1\times10^{-3})}\times300=170K$
so $T_2$ or $T_f=170K$
