For any real gas there is a certain temperature at which the gas obeys the ideal gas laws over a wide range of pressure. This temperature is called Boyle temperature (TB) or Boyle point of the gas. Alternatively, it may be stated as the particular temperature at which the plot of PV vs P for any real gas results in a line parallel to the P-axis in the low-pressure region is called the Boyle temperature of the gas. For example, Boyle temperature of H2 and N2 are – 1560C and 500C respectively. Generally, liquefaction of gas becomes more easier for the gas having higher Boyle temperature.
