calorimetry - 2025 ACF Winter

Question

This technique’s constant-volume form occurs in a bomb vessel. For 10 points each:

[10e] Name this technique that can calculate a sample’s heat capacity, sometimes performed in Styrofoam cups.

ANSWER: calorimetry [accept bomb calorimetry]

[10m] Calorimetry can be used to find the heat of combustion of this thermodynamic cycle, which describes piston engines. This cycle contains two constant-volume steps and includes a power stroke.

ANSWER: Otto cycle

[10h] This other technique complements differential scanning calorimetry by measuring mass changes over time. The quasistatic type of this technique allows samples to reach thermal equilibrium before proceeding.

ANSWER: thermogravimetric analysis [or thermal gravimetric analysis; accept TGA; accept thermogravimetry]
