Answer:Decreases
Explanation:
Given
Volume is held constant that is it is a isochoric process.
We know that
PV=nRT
as n,V& R are constant therefore only variables are
P & T
so [tex]\frac{P_1}{T_1}=\frac{P_2}{T_2}[/tex]
[tex]\frac{P_1}{P_2}=\frac{T_1}{T_2}[/tex]
As [tex]T_1[/tex] is decreasing therefore Pressure must also decrease so that ratio remains constant.
