The influence of the temperature on the values of 0 becomes 
stronger and stronger. Though was only 0,33 at 160°, this 
value has now risen to 0,75. As we already remarked above, not 
a trace of a point of inflection is now found; only the minimum at 
E and the maximum at B of van der Waals’ ordinary isotherm 
have been left.
