A sample of 126 soft X-ray flares (ranging in X-ray class from C3 up to X3) is studied in order to look for possible correlations between various parameters of the flare plasma. It is found that the emission measure (N2V) correlates positively with the electron temperature (T) determined from the Ca XIX resonance line and nearby satellites. Measured values of the maximum value of T (TM) range from 8 to 18 x 10 to the 6th K. Increases in N2V of no more than a factor of 400 from X-ray onset to soft X-ray maximum are observed. The largest increases result from the most intense flares. The limit on the increase of N2V may be important in determining the relative roles of chromospheric evaporation and compression in producing the observed high densities in soft X-ray flare plasmas.
