<strong>Polytropic</strong> <strong>Process</strong> <strong>of</strong> <strong>an</strong> <strong>Ideal</strong> <strong>Gas</strong><br />
• The relationship between the pressure <strong>an</strong>d volume during<br />
compression or exp<strong>an</strong>sion <strong>of</strong> <strong>an</strong> ideal gas c<strong>an</strong> be described<br />
<strong>an</strong>alytically. One form <strong>of</strong> this relationship is given by the<br />
equation<br />
pV<br />
n =<br />
const<strong>an</strong>t<br />
• where n is a const<strong>an</strong>t for the particular process.<br />
• A thermodynamic process described by the above equation is<br />
called a <strong>Polytropic</strong> process.<br />
