## Homework Statement

3.14

(0.5) How is the fractional change in temperature related to [tex]\frac{dT}{T}[/tex] the fractional change in pressure [tex]\frac{dP}{P}[/tex] ?

(IPhO 2006)

## Homework Equations

[tex]PV^{\gamma}=\rm constant[/tex]

## The Attempt at a Solution

nC_vdT=-PdV

**(1)**, dV/dP=-nRT/(P^2)

If I substitute dV in the equation

**(1)**it does not give the right result.

Can someone help me, please? :tongue2:

Thanks my dear friends.
