Glass transition: Difference between revisions

Revision as of 15:16, 19 June 2007

In the laboratory the glass transition is not a sharp transition; its properties change smoothly across $T_{g}$ .

$T_{g}$ increases with a decrease in the observation time, $\tau _{\rm {obs}}$ .
$\Delta H=0$
$\Delta V=0$

See Ref 1.

$\tau _{\rm {obs}}$
