Packet 6: Bonus 15

Calibrating devices for this technique requires correcting for the difference in temperature between the furnace and the sample in a phenomenon called “tau lag.” For 10 points each:
[10m] Thermogravimetric analysis is often paired with what technique that is used to compare the heat capacity of a sample to metal reference standards like indium?
ANSWER: differential scanning calorimetry [or DSC; prompt on calorimetry]
[10h] A sample’s thermal stability can be assessed with DSC by calculating this quantity after introducing air to the furnace. This quantity is defined as the time between when a sample melts and when it begins to decompose under isothermal conditions.
ANSWER: oxidative induction time [or oxidation induction time or OIT]
[10e] DSC is used to produce these diagrams that show discontinuous changes in the analyte’s physical properties on a plot of temperature and composition. Three equilibrium lines meet at the triple point on these diagrams.
ANSWER: phase diagrams
