Maxwell Equation Solved Example

Example

Show that: 

Solution

This example uses the Maxwell Relations Table from the previous blog entry. You can read it here

Lets combine the first and second laws: dU = TdS - pdV

Divide both sides by dV and keep T as a constant:

Note that:

This results in:

Using the Maxwell Relation for A:

This results in:

Since:

This confirms that



The Thermal Properties of Matter

To be able to use Fourier’s law, the thermal conductivity of the material must be known. This property, referred to as a transport propert...
