Answer:

Given:

During Adiabatic process, volume is related to temperature as follows

V \propto \frac{1}{ {T}^{2} }  \\

To find:

Relationship better pressure and temperature

Concept:

We will consider Ideal Gas Equation

PV = nRT\\

Calculation:

V \propto \frac{1}{ {T}^{2} }  \\

 =  >  \frac{nRT}{P}  \propto \frac{1}{ {T}^{2} }  \\

Since, n and R are constants , we can say that :

 =  >  \frac{T}{P}  \propto \frac{1}{ {T}^{2} }  \\

 =  > P \propto \:  {T}^{3}  \\

So final answer is :

 \boxed { \red{P \propto \:  {T}^{3}  }}\\

Answer:

Taking constant "k" , we can say that:

V = k/T²

Now, putting Ideal Gas equation (PV = nRT)

=> nRT/P = k/T²

=> T/P = k"/T² .........[ k" is another constant]

=> P = (constant) T³

So P is directly proportional to T³
