Question

If the volume is held constant, what happens to the pressure of a gas as temperature is decreased? Explain.

Answer 1

Answer:Decreases

Step-by-step 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
`(P_1)/(T_1)=(P_2)/(T_2)`

`(P_1)/(P_2)=(T_1)/(T_2)`

As
`T_1` is decreasing therefore Pressure must also decrease so that ratio remains constant.
