In order to find the factor that the pressure will decrease or increase, we need to analyse the following equation:
[tex]\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}[/tex]This equation means the relation PV/T is always constant, where P is the pressure, V is the volume and T is the temperature.
So, using the given information, we have:
[tex]\begin{gathered} \frac{P_1V}{T_1}=\frac{P_2V}{T_2}\\ \\ \frac{P_1}{T}=\frac{P_2}{1.55T}\\ \\ P_1=\frac{P_2}{1.55}\\ \\ P_2=1.55P_1 \end{gathered}[/tex]That means the pressure will increase by 1.55x.
