Temperature (2)<br />

thermodynamic temperature scale<br />

• (absolute, Kelvin scale)<br />

• pressure vs temperature t of gas at constant t volume<br />

and volume vs temperature of gas at constant<br />

pressure extrapolate <strong>to</strong> zero at - 273.15 o C<br />

• this is “absolute zero”<br />

• unit: Kelvin<br />

• Size of unit of Kelvin scale = that of Celsius scale,<br />

only shift of zero-point<br />

• This is the temperature scale which is used in most of<br />
