On Volume-Recovery Theory .2. Test on Kovacs Original Delta-Data vs T-Data
Kovacs’s volume-recovery data (PVAc; 40 degrees C) can be described by the phenomenological volume-recovery theory within experimental error (+/-2 x 10(-5)). The non-ideal character of the actual temperature jumps has a considerable effect on volume recovery, even in heating tests. Bounds and corrections for these nonidealities are given.
