Know this first
Chemistry questions first require the material, particles or reaction condition to be identified before a formula or rule is selected.

Start with the physical model
Read the configuration once, state the conserved quantity or governing law, and mark any changing geometry, sign convention or limiting condition.
Build the relation
Given C = CV + αP/T
For a quasistatic process,
Therefore C = δQ/dT = CV + P(dV/dT)
Comparison gives dV/
Integrating, V = α ln T + constant, or T = A eV/α
Check before selecting
Check units, sign and one limiting case. A valid result must still fit the original geometry and stated constraint.
OlympIQ exam lens
- ✓Name the governing law before using a formula.
- ✓Keep the stated geometry and direction information explicit.
- ✓Use one unit or limiting-case check.
OlympIQ trap
Do not use C_P or C_V blindly when the process is neither isobaric nor isochoric.
