A differential scanning calorimetry $($DSC$)$ test $($Fig$.4\mathrm{.}31)$ was performed on an $18\mathrm{.}3$ mg sample of

polystyrene. What is the glass transition temperature of the sample? Determine the specific heat of

this PS just before the glass transition temperature has been reached. What is Cp just beyond Tg$?$
