UNIT 07: THERMODYNAMICS

Thermodynamics is one of the core chapters in MDCAT Physics, sitting within the 20% Physics allocation of your 36-question paper.

What this chapter covers:

• Thermal equilibrium and heat
• Molar specific heat of gas
• Work done by a thermodynamic system during a volume change
• First law of thermodynamics
• Specific heat and molar specific heats of a gas
• Relation between molar specific heat at constant volume and constant pressure (Cp − Cv = R)

These subtopics blend conceptual understanding of energy transfer with steady numerical application, placing this chapter across the easy-to-moderate range with pockets of difficulty in the Cp − Cv derivation and multi-step first law numericals.

Mastery here means being equally comfortable defining terms like internal energy and thermal equilibrium as you are applying ΔU = Q − W across isochoric, isobaric, isothermal, and adiabatic processes.

Why this practice set helps:

• Covers every subtopic the PMDC curriculum identifies, plus the supporting concepts textbooks present alongside them
• Every question includes a full explanation of why the correct answer is right and why each other option is wrong
• Built to help you learn faster than passive reading, with nothing the exam may draw from left untouched

Work through this set attentively, and you build both the conceptual clarity and the calculation precision this chapter demands.
